The LM324 is the default quad op-amp of single-supply design: input common mode includes ground, output swings to near ground, and it runs from a 3V to 32V rail. It is one of the few analog parts in true continuous mass production across TI, ST, onsemi and every second-source fab, so availability is not the problem. The two real issues are picking the right grade for the rail (LM2902 caps at 26V, the B-suffix die at 36V, the LV family at 5.5V) and not treating the similarly-packaged LM339 quad comparator as a substitute - it is a different pinout and a different output stage.
Wide-Temperature Grade of the Same Amplifier
Shenzhen Spot Stock (24-48h Dispatch)
The LM324 die specified for the extended automotive/industrial temperature range (about -40 to +125 degC) with the supply capped at 26V instead of 32V.
3V to 26V single supply versus 3V to 32V on the LM324; same input and output swing behavior.
Current-Generation Die at Commodity Pricing
Shenzhen Spot Stock (24-48h Dispatch)
The B-suffix redesign: supply rating raised to 36V, lower supply current, improved ESD structure, same functional behavior and pinout.
3V to 36V; same common-mode and output swing characteristics of the family.
Modern Low-Voltage Family Member
Shenzhen Spot Stock (24-48h Dispatch)
A new 2.7V to 5.5V low-voltage design in the same 14-pin footprint - rail-to-rail output, far faster than the original, but a different silicon.
2.7V to 5.5V only - it will be destroyed on a 12V or 24V rail that the LM324 handled.
Same Die, Two Channels - Not a Same-Socket Part
Shenzhen Spot Stock (24-48h Dispatch)
The dual version of the same single-supply amplifier: identical electrical behavior per channel, in an 8-pin body.
3V to 32V (same family behavior); one output per channel less than the quad.
Q: What is the difference between LM358 and LM324?
A: Channel count and package: LM358 is the dual (SOIC-8 / DIP-8) and LM324 the quad (SOIC-14 / DIP-14) version of the same single-supply amplifier design. Electrically, one channel of each behaves the same way.
Q: Can I use an LM339 comparator instead of an LM324 op-amp?
A: No. Different pinout (supply on pin 3 versus pin 4), open-collector output that cannot source current, and no internal compensation for feedback operation. The two 14-pin chips look like cousins on a schematic and are not interchangeable.
Q: How do I choose between LM324, LM2902 and LM324B?
A: By rail and temperature: LM324 for 32V commercial use, LM2902 for wider temperature range at 26V, LM324B for new designs (36V, current die). LM324LV only for 3.3V / 5V designs built new.
Each amplifier draws 300 µA supply current. Input bias current is 10 nA typical.
Input offset voltage is 300 µV typical, which keeps the DC error low in precision integrators or current-sense circuits.
