Product details

Quad general-purpose op-amp in 14-SOIC — what you're getting

The LM2902DG4: It packs four independent op-amp circuits into the standard SOIC-14 footprint, making it a drop-in for any board that already routes a quad op-amp in that package. Key parametrics: 1.2 MHz gain-bandwidth product, 0.5 V/µs slew rate, 3 mV typical input offset voltage, and 20 nA input bias current. Supply range spans 3 V to 26 V, with each channel drawing 1.4 mA quiescent current and capable of sourcing or sinking 30 mA.

Obsolete — plan your BOM around it

For a new design, do not commit this part to the BOM unless you have a confirmed stock of legacy units or are willing to qualify a pin-compatible replacement.

Slew rate is 0.5 V/µs. Gain-bandwidth product is 1.2 MHz. Input bias is 20 nA and input offset is 3 mV.

Supply current is 1.4 mA per quad.

Frequently asked questions

Where can I buy LM2902DG4?

Since the part is obsolete, it is not available through standard factory distribution. Submit a request with your target quantity and we will confirm availability and current pricing at quote time.

Does LM324 work as a substitute for LM2902DG4?

If your application stays within commercial temperature, the LM324 can work. For industrial or automotive temperature environments, you need a part rated for the full range — consider the LM2902V or LM2902K series in 14-SOIC.
