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.
The Texas Instruments LM2902BIPWR is a quad-channel general-purpose operational amplifier rated for supply spans from 3 V to 36 V. The four amplifiers share a common supply and ground, packaged in a 14-TSSOP (4.40 mm width) for surface-mount assembly.
For a BOM freeze or a long-run production line, this part does not carry the supply-risk flag that NRND or EOL parts do.
Slew rate is 0.5 V/µs. That limits the part to signals below roughly 80 kHz full-scale swing — fine for audio, sensor outputs, and DC levels, but not for video or high-speed pulse amplification.
