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 for automotive signal chains

The Texas Instruments LM2902LVQDRQ1 is a quad (4-circuit) general-purpose operational amplifier qualified to AEC-Q100 for automotive applications. It operates from a single supply spanning 2.7 V to 5.5 V.

Each of the four amplifiers draws 90 µA of supply current.

Temperature range and package — fit for the production line

The 14-SOIC package (3.90 mm body width) is a standard surface-mount footprint that places cleanly on a pick-and-place line and reflows with a typical lead-free profile.

It is ROHS3 compliant and available through independent distribution.

Frequently asked questions

Is LM2902LVQDRQ1 obsolete or active?

The LM2902LVQDRQ1 is Active in production — no end-of-life notice or last-time-buy schedule. It remains a current, manufacturable part for new designs and replacement orders.

Can LM2902LVQDRQ1 replace standard LM2902?

Yes, the LM2902LVQDRQ1 is pin-compatible with the standard LM2902 in the 14-SOIC package. The LV variant operates down to 2.7 V (vs. 3 V typical for the standard part) and draws lower quiescent current, making it a direct upgrade for power-sensitive or lower-voltage designs without a board layout change.

What is the gain bandwidth product of LM2902LVQDRQ1?

The gain-bandwidth product is 1 MHz. This sets the usable frequency range for closed-loop gain stages — for example, a gain-of-10 amplifier maintains flat response to about 100 kHz.
