Product details

Quad op-amp, 1.2 MHz GBW — the general-purpose workhorse

Supply span runs from 3 V to 30 V, so it works off a single 5 V logic rail, a 12 V industrial bus, or dual ±15 V supplies without a separate regulator. Total quiescent current for all four amplifiers is 1.4 mA — roughly 350 µA per channel — which keeps the thermal rise low in the SOIC package.

At unity gain, the 0.5 V/µs slew rate supports a full 20 Vpp output swing up to about 8 kHz before slew-induced distortion sets in. For smaller swings the frequency ceiling scales proportionally. If your application needs to reproduce a 10 kHz square wave cleanly at 10 Vpp, this part will round the edges — look at a faster op-amp family instead. Input offset voltage is 2 mV typical, input bias current 15 nA. Those numbers are fine for DC-coupled signals from a few millivolts up; for microvolt-level precision or high-source-impedance transducers, a precision op-amp with lower Vos and Ib would be a better fit.

Active lifecycle — no end-of-life surprise

The base product number is LM324, one of the most widely second-sourced quad op-amp families in the industry. The 'A' suffix indicates tighter offset voltage limits than the original LM324. If your assembly line prefers Cut Tape, that option is also listed.

Frequently asked questions

Can I use LM324ADRG4 as a replacement for LM324N?

Yes, electrically the LM324ADRG4 is a functional equivalent to the LM324N. The key difference is the package: LM324N is a DIP-14 through-hole, while the LM324ADRG4 is a 14-SOIC surface-mount. The 'A' suffix means tighter input offset voltage (2 mV typical vs 3 mV for the original LM324). Pinout is identical across the LM324 family.

How many channels does LM324ADRG4 have?

Four independent op-amp channels in a single 14-SOIC package. Total supply current for all four channels is 1.4 mA typical.
