Mixed assortment of different op-amps to do some practice

[analogo]

I am studying op-amps at the moment and I read everywhere that there are many different kinds of op-amps that one can buy. I would like to play with these different classes to understand how they work and their gotchas. I have only one op-amp at the moment (LM358) and I would like to order some other.

What categories of op-amps should I care about? What are good (almost "jelly bean") representatives of each class and of the limitations of that class?

The only particular categories that I know of (but I have no examples of) are

• rail-to-rail op-amps
• bipolar op-amps
• CMOS op-amps

What else is out there?

[MosherIV]

Bi-polar - some op-amp are marketed as Single rail but in reality if you bias them mid way, any opamp can run from single rail.

Get some JFET op-amps, they have very high input impedance but are more suseptable to static.

Some recommendations:

of course, one should have some of the 'classics', even if only as a bad example.
And some of them are passable and quite forgiving.

LM301, LM741, LM324, TL071/2/4 (or 08x)

intermediary Generation
NS LPC660IN OPA, Low-Power quad CMOS, r2r-out, <1mW, 2fAb ~3mVos, 0.11V/µs 0.35MHz CMRR>63db >1TOhm
LTC LT1013/1014 OPA, Dual/Quad precision low noise, os<300µV/1nA, Ib<30nA, Avol2.5V/µV typ, 500kHz 0.4V/µs, CMRR114db typ.
LTC LT1077 Micropower/precision OPA, 250kHz 0.12V/µs, single supply; Ib<11nA, os<60µV/350pA, 60µA max.
NE5532/5534, low noise OPAs. the audio people seem to love them
AD822 Dual precision, r2r, Low-Power, FET-Input OP,
AD845 Precision, 16MHz CBFET OPA,
TLC2272/4 OPA, LinCMOS Dual/Quad r2r, low noise, typ Ib1pA os300µV

And now some nice ones:

LTC LT1468/1469 bipolar 90MHz, 22V/ms 16-Bit Accurate Operational Amplifier
despite its performance, it behaves rock-solid! Solved many problems for me.

LT1800/1801 OPA, Low Power R2R In/Out Precision 80MHz

AD8512 OPA, dual JFET Precision, Wideband, very low Noise, low Bias Current

AD8522 Dual Zero-Drift, Single-Supply, r2r Input/Output OPA

ADA4077 OPA, High Precision, Low Offset and Drift, 4MHz 7nV/Sqrt(Hz) (NextGen OPxx77)

LMP2021MA OPA, Zero-Drift, Low Noise EMI hardened, r2r out

TLE2021 OPA, Excalibur Precision, High-Speed, Low-Power, ext. Adj. (and other TLE202x)

TLE214x OPA, single/dual/quad Excalibur BiFET Low-Noise High-Speed Precision;

ADA4857 OPA, ultra-low Distortion, low Noise, high Speed, power-down Input

LMH6612 OPA, Dual, Single Supply 345 MHz Rail-to-Rail Output

Neomys Sapiens compiled a very comprehensive selection.

I would only add the LM3900 and the LM13700 transconductance amps.

Also, for comparator use, get yourself some real devices: The LM339 and the LM311.

[Neomys Sapiens]

Ok, I intentionally left those out, as well as CFAs, Power-OPAs, Combo-components like LM10, Differential OPAs, Hybrids akin to the LH0022 etc

[schmitt trigger]

you may be right...transconductance amps are a little advanced.

But the comparator selection I would definitively consider.

[Neomys Sapiens]

Power-OPAs (affordable, of course, there's  APEX)
TI OPA552 High-Voltage, High-Current Operational Amplifier; OT/OC protected
TI OPA549S High-Voltage, High-Current Operational Amplifier; OT/OC protected,
TI OPA569 Power Op Amp, Output Signal Swings Within 200mV of Rails at 2A Output Current; 1.2MHz 1.2V/µs
LT LT1970 500mA Power Op Amp with Adjustable Precision Current Limit
NS LM675T Power OPA, 3A max, 5.5MHzGBW, 8V/µs 1mVOS, Gain 90dB, OT/OC prot.
Siemens TCA1365 Power-OPA, 4A 42V max, SC/Th-prot.,

ok, I'll leave the other categories to someone else...

The LM358 dual and LM324 quad opamps use low power so some common things in normal opamps have been left out. The are noisy (hiss), have crossover distortion (look in Google) and cannot produce high level outputs above 2kHz. Audio opamps do not have these awful problems.

[David Hess]

I am just going to list inexpensive parts suitable for learning.

LM358 (dual) and LM324 (quad) - General purpose operational amplifiers, Single supply inputs and output
LM393 (dual) and LM339 (quad) - General purpose 1 microsecond comparators, Single supply inputs, Comparator version of the LM358 and LM324 above
LM301A (single) - Input range includes positive supply (1), Supports clamping through compensation pin (2), Use instead of 741 types
OP07 (single) - General purpose bipolar precision
TL051 (single) and TL052 (dual) - JFET input, Low input bias current, High bandwidth, High slew rate, Input range includes positive supply (1), Faster higher precision replacement for TL071 and TL081 types, Use instead of TL071 and TL081 types

(1) Operational amplifiers which support input voltages to the positive supply are useful for high side current sensing.
(2) Support for clamping is very rare and useful for constant voltage constant current power supplies.  The LM301A is also more suitable for use as a comparator than most other operational amplifiers when no compensation is used.

Just for experiment on the breadboard, there is not much use for super fast OPs, like more than 20 MHz GBW. Usually one can do much with the more cheaper / jelly bean OPs. Learning electronics is also about learning the limits of the parts. Thus using no so good parts can help.

The LM358 is still nice for the simple stuff and the breadboard and they are dirt cheap.

Common Rail to Rail types are TS912 and MCP6002. They are CMOS and thus also good for high impedance things.

Classic JFET Ops are TL07x (or more noisy TL08x) series and similar LF412 / LF351.

The OP07 is a classic precision OP. The OP27 (similar to LT1007) is the faster, lower noise version.

The NE5532/NE5534 are classics for audio.
