LM124/LM224/LM324/LM2902 is a low power quad operational amplifier with high gain and internal frequency compensation. It can operate from a single power supply or split power supplies and is suitable for transducer amplifiers, DC gain blocks, and other conventional op amp circuits.
The LM124 series and its related parts (LM224, LM324, LM2902) are low‑power quad operational amplifiers designed for single‑supply operation over a wide voltage range. They feature internally frequency‑compensated stages, low input bias current, and the ability to operate from ground‑referenced supplies.

| Supply voltage range | Single supply 3 V to 32 V or dual supplies +1.5 V to +16 V |
|---|---|
| Unity‑gain bandwidth | 1 MHz |
| Input bias current | 45 nA (temperature compensated) |
| Input offset voltage | 2 mV |
| Maximum output short‑circuit current | ≈ 40 mA per amplifier |
It can operate from a single supply of 3 V to 32 V or from dual supplies of +1.5 V to +16 V.
The unity‑gain bandwidth is about 1 MHz.
Each amplifier can tolerate a short‑circuit current of roughly 40 mA.
