Product details

Active quad op-amp in SOIC-14 — what the supply range means for your rail

The 45 nA input bias current (typical) keeps DC errors low in high-impedance circuits like photodiode amplifiers, though the 2 mV input offset means you budget a trim or choose a tighter grade for precision work.

Active lifecycle — no end-of-life surprises

Listed as Active with no NRND or LTB flags. For dual-sourcing, any standard LM324 quad op-amp in SOIC-14 is pin-compatible, but the LinCMOS variant draws only 1.5 mA supply current typical — lower than the bipolar LM324's ~3 mA — which matters in power-budgeted designs.

Frequently asked questions

Is LM324M/NOPB a direct replacement for other LM324 variants?

Yes — the LM324M/NOPB is pin-compatible with all standard LM324 quad op-amps in the SOIC-14 footprint. The LinCMOS construction gives it a lower supply current (1.5 mA typical) than bipolar LM324 parts, so check that your existing design's compensation network doesn't rely on the higher slew rate of a faster variant.
