Supply Chain & Allocation Reality:

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)

Electrical & Core Specs:

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.

Compatibility & Drop-In Notes: The substitution to make when a design must keep working below 0 degC or above +70 degC and the original LM324 was only a commercial-grade part. Verify the 26V ceiling against the actual rail.
Package & Solder Footprint: Same SOIC-14 / DIP-14 pinout (OUT1=1, V+=4, GND=11, OUT4=14 pattern of the family - match the datasheet drawing).

Current-Generation Die at Commodity Pricing

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

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.

Compatibility & Drop-In Notes: For new stocks and new builds this is the part to standardize on. In legacy circuits it behaves like the original LM324 within the original rail; the extra supply headroom only adds margin.
Package & Solder Footprint: SOIC-14 / TSSOP-14 pinouts follow the standard quad-op-amp arrangement - confirm against the vendor drawing before SMD placement.

Modern Low-Voltage Family Member

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

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.

Compatibility & Drop-In Notes: Only for 3.3V / 5V designs. In an existing LM324 socket powered from 12V or higher this part is the wrong direction entirely; in a new low-voltage design it is the modern replacement.
Package & Solder Footprint: SOIC-14 footprint matches the family; pinout per the LV datasheet.

Same Die, Two Channels - Not a Same-Socket Part

Shenzhen Spot Stock (24-48h Dispatch)

Electrical & Core Specs:

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.

Compatibility & Drop-In Notes: The classic pairing question: LM358 and LM324 differ in channel count and package, not in amplifier behavior. Two LM358s on an adapter are never a clean LM324 replacement - use the correct package.
Package & Solder Footprint: SOIC-8 / DIP-8 versus SOIC-14 / DIP-14 - a different footprint, listed here for the comparison, not as a socket substitute.
Shenzhen Warehouse Stock & MOQ: Deepest stock of the whole family; original factory reels and batch packaging.

Buyer & Quality Checklist for Sourcing Alternatives
  • Do not substitute the LM339 quad comparator for an LM324 (or the reverse): the 14-pin pinouts differ (on the LM324 the supply is V+ = pin 4 and GND = pin 11; on the LM339 V+ = pin 3 and GND = pin 12, with a different arrangement of inputs and outputs), the comparator output is open-collector and cannot source current, and a comparator is not internally compensated for unity-gain feedback.
  • Match the grade to the rail: LM2902 is a 26V part, the LM324B die is 36V, and LM324LV is a 5.5V part. Cross-fitting grades is the most common way to kill an otherwise correct substitution.
  • The family cannot pull its output all the way to the positive rail (about V+ minus 1.5V class) and shows crossover distortion when the output stage transitions while sinking current - fine for DC and control loops, a known compromise in audio paths.
  • Inputs work at ground (common mode includes V-) but not near V+: keep sensor front ends within the documented input range or the output phase-inverts.
  • When replacing a worn-out LM324 in a battery product with the LV family, check that every supply pin in the circuit is now on 5V - the LV part dies instantly on legacy 12V rails.
Frequently Asked Technical Questions

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.

Technical Details & Description

Quad op-amp with 1.2 MHz GBW and automotive temp range

The Texas Instruments LM2902KAVQDR is a quad general-purpose operational amplifier in a 14-SOIC package, part of the Automotive AEC-Q100 series. It delivers a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs, suiting it for signal conditioning in automotive and industrial control loops where four independent amplifiers share a single supply rail. Operating from a single supply of 3 V to 30 V, the device draws 1.4 mA total across all four channels — a reasonable quiescent budget for a multi-channel sensor interface running off an unregulated battery line.

Parametric fit for signal-chain design

Input offset voltage is 3 mV typical, and input bias current is 20 nA typical — these levels are adequate for non-critical sensor buffering or level-shifting stages where the signal amplitude is above 100 mV and source impedance is under 10 kΩ.

Lifecycle and compliance

The base product number is LM2902, which shares pinout and parametric compatibility with the broader LM2902 family. No official successor or cross-reference is required for this active part.
