Hi Today we're going to take a look at a whole bunch of different jelly bean components as they're called or industry standard components that you pretty much expected to know right off the top of your head. Because you'll use these parts over and over and over again, in your career and in the tear down videos. Uh, you've seen me do. You'll no doubt have seen these count these parts countless times and when I'm doing a tear down, I don't even have to say anything more than the part number because you should instantly know what these chips are.

They're called jelly bean components, so it's very important for any design engineer to have intimate knowledge of these a whole bunch of these jelly bean components so that you can just go. Oh yeah, I need this chip for this particular task here. Oh yeah, just throw in the jelly bean part because right off the top of your head you know the specs. You know it's going to do the job.

It's going to be good enough. And that's why these parts are everywhere. And as you'll see in our first one here, it's been around for like 45 years and this is where most of these jelly bean parts have now. My definition for a jelly bean part is: A It's been around for a long time.

A B It's available from many different manufacturers, Uh, C It's uh, like A cheap, it's dirt cheap, and uh, for it's available because available from many different manufacturers, it's so ubiquitous it's just like, typically there's millions of these things in stock, even during, uh, like, times we have like this, with uh, the component shortages and things like that, you can almost certainly still get these jelly bean components from someone, because if you're the manufacturer you've specified into your bill of materials doesn't have it for some reason. Well, you can pretty much throw in any uh, equivalent part with the same part number and you know it's going to do the job because it's a jelly bean component. The first one we're going to take a look at here is the Lm358. It's a dual bipolar Op-amp so if you need just a basic run-of-the-mill Op amp to just do basic stuff, then the Lm358 is a great choice.

It's a dual Op-amp and they specifically call it an industry standard Op Amp because it pretty much is. So it's two Op independent Op amps in the one package. There's pretty much no reason to use a single, uh, like Op-amp jelly bean component. If you're gonna like put and choose an Op Jelly Bean Op-amp you might as well choose the Lm358 because it's a dual one.

even if you don't use the second Op-amp hey, it adds flexibility to the design. Later, you've got that second Op-amp and you might be able to budget in to your circuit or something like that. At least you have it available. it's designed in.

So yeah, Dual Op-amp handy. and as you can see, it's available for many different manufacturers here. Like I've only got three of them, but there's dozens and dozens, including like no-name ones from China or whatever. So as you can see, the date up here look June 1976.

This is 45 years old and it's still sold in the millions of billions. I don't know how many of these are sold every year, but it is the go-to Op Amp. The Lm 358, also known as the Lm2904 and 2904 is just like a higher temperature, uh grade version. sort of like a more, uh, commercial industrial temperature range than the Lm358 and it's available in different versions the B version and the A version and stuff like that, and there are some slight spec differences up between them.

But if you're designing in a jelly bean component into your circuit, then you generally aren't pushing the specs. You don't really care whether or not you get the A version or the B version or anything like that. If you're worried about that sort of thing, then you're not really in the jelly bean category, so to speak. So yeah, I'm just going to run with that description anyway.

Sometimes you might want to do that, but as a general rule, no, if you're after tighter specs, you'll go for a more non-jelly bean component. Some features of the Lm358: It works anywhere from three to 36 volts. Brilliant. So huge, Wide ranging operation that includes both unipolar and bipolar supply.

so single supply or a split supply. it's relatively low power. 300 microamps per amplifier that's not too shabby. It's got a unity gain bandwidth of 1.2 megahertz.

Once again, that's not too shabby a meg and it is unity gain stable. So it's stable. It's not going to oscillate with a gain of one. and uh.

Also another important thing. the common mode input range includes ground, so that enables direct as it says here, direct sensing near ground. And if you go over to say, the Rome data sheet it actually says calls it a ground sense operational amplifier and that's a huge advantage in terms of like, if you want to do like a low side current shunt measurement or something like a non-critical current shunt measurement just you know to a modicum accuracy, then it's a pretty good decent job for that. It's got a low input offset voltage, low, uh, three millivolts.

But once again, this is a jelly bean component jelly bean specs. but this is just a guaranteed figure. The Uh, the typical figure is like 300 microvolts. It's an order of magnitude better than that, but just be aware that that offset voltage and the Emi are filters here.

If you go down here, you can see that that is uh, specific to the B version. here. Three millivolts like that If you go for the regular A version, which is what's available from other manufacturers in the I'm not sure if Ti are the only ones that do A B version, just be aware of that, but the A1, you know once again, it's around one millivolt. typical something like that, so you know good enough, but you can.

It's nice to know that you can get like a tighter version uh, available from Ti in the B version, but if you're designing this in, you have to be aware that that you may be limiting yourself to one manufacturer. So if you designed it in, once again, a typical one millivolt, something like that, the St1 over here one millivolt, so you know, but that's good enough for a ton of applications. That's why it's a jelly bean part, and I won't bore you with all the other specifications and things like that. Just suffice it to say that this is A, you know, just a nice general purpose Op-amp for non-critical applications.

That's why you're going to use it. And as you can see here, it's a Bipolar amplifier design. Another, that Cmos rubbish. We'll look at that in a minute and so it's not going to give you rail-to-rail uh, performance.

I'll show you one that does in a minute. And the great thing about Jelly bean components is they're typically available in many different packages. Look at this: eight different packages from Ti here. Um, like a P-dips like your regular, you know, dip, hobby ones, your Sos, your sock 23s, your T-stops your soics, your ceramic packages, your Lccc packages and stuff like that, and you can see those over on the data sheet here.

St ones are available in four different Dfn packages, but of course, you have to be careful. if you specified in, say, the Stdfn package here, you might not be able to get that from Ti for example, or from someone like Rome for example. No Dfn there. So then just be careful.

But in general, if you're choosing a jelly bean component, you're typically going to use a jelly bean footprint as well. so you can see some differences in here in the spec. Like this: Rom one is like four and a half millivolts maximum and stuff like that. the input bias current by the way.

20 nano amps? uh, pretty good for bipolar stuff. And the other great thing about jelly bean components is the pin outs are going to be identical across all the chips. In fact, this is the industry standard pin out for a dual Op amp. So there you have it.

The Lm358 is my pick for the Jelly Bean. Uh, just the bipolar Op amp. It happens to be a dual one. I don't really have a Jelly Bean single Op amp in a 741 or whatever.

just like Lm358 comes in the same package. Anyway, you might as well get a jewel jobby. The Lm358 is still going strong after 45 years, and that's why it's my pick for the Jelly Bean Op-amp Next up is a Jelly Bean Fit Op Amp and well, this one's hard to beat as well because it's September 1978 here and it's a classic Tl07 series. The Tl071 is the single, 072 is the dual, 074 is the quad.

So really, you know. pretty easy to remember Once again, available for many different manufacturers and it's kind of a little bit better and a little bit worse than the Lm358. Um, you know it's got a reasonably high slew rate. The offset voltage is one millivolt here.

Uh. offset drift Two micro volts? uh, per degree C It does have higher power consumption though, even though it's a an actual fit input Op-amp and you can see up here. it's actually uh, designated as a low noise fit input operational amplifier. But in terms of noise, um, it's actually on par.

There you go. Input voltage noise. There, we're talking about. you know, nine? uh, micro volts, A peak to peak.

That's a typical, whereas the Lm358 is actually only a typical three micro volts are peak to peak. It does have a lower noise density though than the 358, which is about 40 nano volts per root hertz and the 07 one is about 18 nano volts are per root hertz at one kilohertz there. So you know a lower noise density, but in terms of input noise and stuff like that. but it does have a low total harmonic distortion 0.03 This is why it's very common.

You'll find these in lots of audio designs and things like that, and it does have a bigger voltage range as well. It'll go from 4.5 to 40 volts. So plus minus 20 volt supply. Pretty impressive.

So you might be wondering why it's actually got a higher power consumption than the Lm358. even though it's a a fit thing is because well, it's a fit on the input here. But as you can see, it's basically a bipolar design. It just has a fit input front end like this.

This is why it's still relatively high, uh, power consumption. But of course the big advantage that fit input Op amps give you is you're talking pico amps. Now you're talking typical plus minus one, uh, maximum plus 120. So it varies, uh, a fair bit.

but this is like three orders of magnitude. It's a thousand times less than the uh nano amps or tens of nano ants you'll get in a bipolar input uh design. So this is why you want to go for the and then the input offset current as well. Like you're down in like like Femto amps, right? 500 Femto amps.

Pretty low stuff, so that's the advantage of the fat design compared to the bipolar design. But apart from that like no, I prefer the three Five eight. I don't like the Oh seven twos are nice fit input ones, but they're not my preferred jelly bean Op amp just for general applications because the Lm358 and the next one we'll see as well is also the four channel version of the 358 is a lower power consumption and it can do ground sensing as well. The input common mode range includes ground.

As I said, great for current sensing, single supply applications. Something like that. Whereas the Tl07 Um series is not really designed. uh, for that, it won't sense to ground, its output will go to the positive rail, but it's not a true rail-to-rail output device.

and well, yeah, you'd want to have specific reasons for going to the Tl074, but this is it's. been around once again for like 40 plus years. It is a lot of people's go-to op-amp especially if you need fed input. So what if you like the Lm358 but you kind of want that fit input niceness as well as well as are the ground sensing and single supply applications.

Well, I've got the chip for you. The good thing about this one is that you don't have to remember the part number. It's the same. It's the 358 again, but it's the Lmv.

V stands for voltage because it's a lower voltage version of the part, but it is a Cmos version. It's not a Bipolar and it's rail to rail, um. output. operational amplifier as well as the Lm358 is not there.

But apart from that, very, um, similar specs, you know, offset? uh, typical offset? uh voltage. It's got rail to rail output. As I said, one megahertz gain bandwidth product, which is good enough for a lot of applications. Relatively low noise.

but the uh kicker is that because it's a Cmos version, the input bias current is only 10 pico amps, so three orders of magnitude lower. We're looking at nano antennas and nano amps before now we're looking at tens of pico amps. So if you're you know, like a very high input impedance? uh, stuff. Things like that, that's where you want to go.

Uh, it's got lower current as well. 70 microamps per channel? Pretty good once again. Unity gain stable Um, and some versions have the Rfi and Emi filter as well. but good thing is it goes down lower voltage even and goes down to 2.5 volts guaranteed.

It actually operates a little bit below that. Um, which is good for like single Lithium cell applications, something like that, You might want to use this. I use one, and in fact I use the Lmv 321 in my uh, micro current and I've done a video on that where you know you can have a trap with using different brands of this sort of thing. Yeah, so I've actually done a video on that where I used a jelly bean part.

But yeah, there were differences between manufacturers, so I recommend going and have a look at that one because that's a real fascinating trap for young players in like using jelly bean parts like this. I thought they were all the same, but it turns out there was a slight difference in capacitive loading and with stability with capacitive loading where you can come agazer. and once again it's available in a bunch of Uh packages as well. Uh, absolutely terrific and lots of application.

Countless applications for this but one of the downsides is its maximum voltage is only 5.5 volts. So you know, great for like, any sort of like battery-powered sort of like low-power uh, supply something like that. You might want to look at the Lmv version instead of just the regular Lm version, but apart from that it's pretty much an identical Um Op amp. And the good thing is it is available in a single version.

You can get like a little slot 23 joby and stuff like that all the regular um, three five eight. so the single one is three three two one or the three five eight for the dual as we're used to. So as you can see, it's a just a Cmos fat version of the Lm358 and you get some advantages with that. Um, like you can go once again you can go rail to rail output voltage.

There's basically no drop in these output driver transistors here like you'll get with a Bipolar Op amp. So really good for battery powered supplies and where you have to go right to the rail. Winner! Now, of course, just like any Op-amp you can actually use this with a split supply, but you are limited to that 5.5 volts maximum. so you can go plus minus 2.5 volts or a little bit above that.

No problems whatsoever, but you can't go plus minus 5 volts for example. It's not going to do it. You'll have to go back to the Lm358 for that or choose another option. And once again, available in a whole bunch of different packages like this and uh, single and dual.

So and Inda. We'll have a look at the Sec a quad version as well. So yeah, the Lmv 358. That's my recommendation for a Cmos Jelly Bean Jewel Op Amp or single.

So I hear you asking Dave. I really do need a Jelly Bean Quad Op-amp Okay, it's the Lm324 Absolute Classic. In fact, it's probably more well known than the Three Five Eight. The Three Two Four is.

basically think of it as a quad version of the Lm358 and if you go to some manufacturers here, they will actually tell you where is it. Look Rome, uh. ground sense operation. Look, Lm358 Lm324.

It's on the same data sheet because they're essentially the same part. It's just basically a Uh Quad version. Really nice. Same specs, three volts to 32 volts, and once again, that can work dual supply.

plus minus Uh one and a half volts up. It's got 800 microamps typical. There common mode includes a range as well so you can get your ground sensing and stuff like that. The offset voltage is pretty much the same as before input offset current.

Once again, you're in the uh, nano amps or tens of nano amps range. You're not down in peak ramps because this is a bipolar Op amp just like the Lm358. But apart from that, it's pretty much identical. Go and check the specs for yourself and you should know all these specs.

You should learn them off by heart. and it's you know. There's little subtle differences here and there, but basically quad version of the Ln 358. That's why the Lm324 gets my vote for the Jelly Bean Quad Op-amp And as we saw before, the Lmv-358 also includes the Lmv-324 You can get a quad version in the Cmos exactly the same.

See how easy this is? If you know the 358 and the 324, then you know they just add the V for the Cmos version and wow. These like four of these cover a whole ton of different applications. It's it's unbelievable. This is why they still used 45 years later.

and the Lm324 is basically the industry standard uh, quad Op amp. pin out here with the annoyingly the rails in this position. Positive on this side over here and negative over here. Always hated it.

but uh, that's the industry standard. It probably started with the Lm324. and just for completeness, yes, you can actually get a single version of the Lm324 and the Lm3258. It's called the Lm321 here hasn't been around quite as long.

I mean, this data sheet here February 2001. I don't know if it was available before that actually, but um, that once again, it's exactly the same as the only Three Five Eight, Three Two Four in a single package. But as I said, I virtually don't design in a single Op amp like I have designed in the Lmv. Uh, three, Two One in like a tiny little, uh, you know, slot 23 or something like that.

you're looking at saving space and pin count. Yeah, you might do that, but I typically wouldn't. If I'm going for like an Sl8 or something like that or a dip 8. Um, old school, then I'm pretty much going to put in the dual Op amp instead of the Lm321.

But this is not really a recommendation because to me, the Lm321 is not really a Jelly bean Op amp. Because if you just go over to Digikey here. okay, it's available from Ti and on semi. but look.

Zero stock, Zero stock on on all of Digikey. Go to Uh Mauser here. Okay, they've got 140 000 on order. Great.

But on order. on order. on order. That's it.

You can't get stock of this thing. Uh, so it doesn't meet the requirement for the jelly bean, and it's more expensive than the Three Five Eight. So what's the point? Look, the cheapest price on digikey. 22 cents here.

Okay, if you go to Aliexpress or something you might be able to, you know you're going to be able to get it cheaper. But the 358 in stock look 1.8 million in stock at 12 cents each. It's It's a complete no-brainer This is why I would never really design in just the Lm. just the generic Lm 321 over the Lm358.

You get that extra Op-amp for less price, more available, complete no-brainer So I it's just. I'm just including that for completeness. It's not really a jelly bean part, All right. I'm not going to hear the end of it unless I mentioned the Lm741.

For all the 741 fanboys out there, man, it is one of your traditional jelly bean Op amps. but for me, it just I I There's very little reason to use the 741 these days. Just go for the Lm358 or 321 even. or you know, 324.

And the other thing is, well, yeah, you can sort of get some available in like old school packages and look at this old school dip at 91 cents each, it's like yeah, nah, there's a better option than this. And it's uh, the uh. basically the dual version of the 741. And it's the Um Rc4558 also known as the Mc400 Mc400458 and we can take a squeeze at that.

And here you go. This goes right back to March 1976. Here it's and it's the dual. Basically, it tells you it's a dual.

version of the Um 741. So really, there's no reason to use the 741 these days. I would just go for the dual version. And as you can see like, availability is better.

And also if we sort by price here, yeah, check it out. 183 000 available? Um, like 10 cents. Why you use the 741? I've got no idea. So yeah, sorry to all your 741 fanboys, but now you'd use the Four.

Double Five Eight is just going to be is just a better option all round. But once again, like this, it's similar. sort of. uh, specs.

You know, it's fairly robust, little beastie, You know, short circuit protection. all this sort of stuff, but it it's not. It doesn't include ground sensing. it's not rail derail, it's just a yeah knob.

so it's nothing special. but it does have relatively low noise. Um, which is why you'll often find the Four Double Five Eight in. uh, lots of audio.

uh circuits. you know, preamps and uh things like that. It's quite a common part out, probably. you know, the common jelly bean audio op amp I guess.

But you don't get any niceties like ground sensing or rail to rail or anything like that. so it's just like your old school bipolar Op amp. Having said that, I will not survive the comment section unless I mention the Ne Ne5532. You could say this is the de facto standard audio op amp.

I guess I won't go into the reasons why, but low noise, grunty little thing. It's good, decent thd performance and everything else. So you'll find this in a ton of Uh audio designs. and once again, it's like 1979.

it goes way way back and there's a whole bunch of audio files out there who will not touch an audio design unless it has double 532 Uh chips in and you'll actually see these are often advertised in the Uh product design that it uses this chip. But it's not the best performance chip out there. but I guess it's the Jelly Bean of you know, decent performance audio Op amps. So yeah, you will see this one out there a lot, so it's well worth.

uh, familiar. Familiarizing yourself with it, make yourself familiar with it. So although the definition of Jelly Bean components kind of implies meh specs, I kind of feel obligated to include the Jelly Bean Precision Op Amp which is the Op 07 and this one is going back of course 1983. Fantastic! So as the precision name implies here, it basically means it's got low offset voltage.

It's it's precise. doesn't need any like external trimming or anything like that. So you know I kind of have like the old school uh talking points like uh, comparing it to like chopper amplifiers and stuff like that because back in the day to get low offset voltage you had to use a chopper amplifier. but when uh you know the Op-amp Op-07 came along.

It was sort of no you didn't have to do that, It was kind of like it was just low offset of voltage built in and it's got you know a decent Uh voltage range as well. plus minus 18 Volts here can work down to plus minus three and once again this is available in different grades from different manufacturers and stuff like that. But if we look at like the Oppo 7 C here input Offset Voltage typically like in the order of you know, sub 100 micro volts here like 60 odd micro volts something like that. So if you want to step up uh from like the Lm358 or 324 or something like that because of the offset voltage, then this is the one that you would design in would be the Oppo Seven.

and because it is a bipolar joby, it's actually uh, nano amps input current. It's not uh, pico amps. so yeah, sorry for all you pico amp fan boys. But unfortunately one of the major downsides is that it's not a ground sensing or rail to rail Op amp.

So think of it as like a precision Lmr741 or Double Four, Double Five Eight for example. You can also get uh, dual versions of this and uh, quad as well available in different part numbers. You can go uh, look at those over your own accord and one of the things is because it's like a 741. It does actually have offset pins, so you can have offset capability so you can get a trimmer in there and trim it to even better specs.

But if you're after a precision Op Amp these days, if you're designing in like, you know, fairly tight specs, then you know there's lots of other alternatives. the Oppo 7, But it is a generic part available for lots of different manufacturers at a reasonable cost. So it certainly has been around for like 30 40 years. So it certainly gets, um, the Jelly Bean tick of approval.

So there you have it. That's my list of kind of like the Top Five I guess. Um, Jelly Bean Op Amps. You know, the Lmr324, Lm358, the Uh Tl070 series, um, the Lmv Uh series, and the old School 4005.8 for kind of like audio or general purpose bipolar stuff, and um, the Oppo Seven for the precision.

As a bonus, they're so kind of like Top Five Jelly Bean Uh Op Amp. So as always, leave it in the comments down below if you think I've missed something because I'm sure everyone will have their favorite. What is your favorite? What is your most used? What is your go-to Jelly Bean component? Please leave it in the comments I want to know. And uh, beginners out there.

These chips. You're kind of like expected to know these. Not like every in-depth specification. like you don't have to memorize absolutely everything in here, but you should know the basic order of magnitude of the offset voltages of these.

and like features like do they have ground, uh, current sensing output, uh, rail derail capability and stuff like that and you should be able to just recognize and use these parts right off the bat. You should have them in stock, You should have them in your Cad library so you can just drop them into your designs. and you should just be able to. At a job interview or something somebody asked you.

Oh, you know, give us a name as an Op Amp, right? You'll be able to tell them. Oh yeah, I use the Lm358 because it's a dual joby and it's nice. it does ground sensing and it's just you know, across different manufacturers, it's cheap, really available. It's been available for like 40 years.

it's you know, Bobby Dazzler. So anyway, I hope you enjoyed that. If you did, please give it a big thumbs up and certainly let me know in the comments down below and by the thumbs up, if I get a lot of thumbs up and views on this, I'll do more. Um, because like I haven't even touched on uh, you know, comparators and all sorts of other analog devices, let alone digital ones.

I'll do a like a little mini series of jelly bean components as you can know. So anyway, I hope you found that useful and as always you can discuss uh either in the comments down below or over on the Eev blog forum where I have a thread for each and every one of these videos. In fact, I did want this video to like cover more things, but I started yapping on about Op Amps so it's dedicated to Op Amps. But anyway, and also, check out my Odyssey channel.

I've got more than 60 000 subscribers over on Odyssey as well if you're sick of the Youtubey ads Anyway, hope you enjoyed it. Catch you next time you.
