LM124, LM124A, LM224, LM224A LM324, LM324A, LM324Y, LM2902, LM2902Q are a series of four operational amplifiers produced by TI. They have wide range supply voltages (single supply voltage 3V to 30V, dual supply voltage 3V to 26V), low supply current consumption (independent of supply voltage), common mode input voltage range includes ground (reliable detection of ground nearby voltages), low input bias and offset parameters (input offset voltage 3mV typical, A version 2mV typical; input offset current 2nA typical; input bias current 20nA typical, A version 15nA typical) and equal to maximum rated supply voltage differential input voltage range (32V, LM2902 and LM2902Q is 26V).
The LM124/LM124A, LM224/LM224A, LM324/LM324A/LM324Y, and LM2902/LM2902Q families are four‑channel operational amplifiers designed for single‑supply operation over a wide voltage range. They are suitable for transducer amplifiers, DC amplification blocks, and typical op‑amp circuits, and can be used in automotive‑grade applications.
The devices are offered in several package types (D, DB, N, FK, J, W, PW, Y) with corresponding temperature ratings and power‑dissipation limits. Absolute‑maximum ratings, typical electrical parameters, and recommended operating conditions are detailed in the datasheet.
| Supply voltage range (single supply) | 3 V to 30 V (LM2902/LM2902Q 3 V to 26 V) |
|---|---|
| Power dissipation (D package) | 900 mW |
The LM124 series can operate from a single supply of 3 V up to 30 V (LM2902 and LM2902Q are limited to 26 V).
