LM124/LM224/LM324/LM2902 is a low power quad operational amplifier that can be powered by a single power supply, the input common mode voltage range includes ground, the output voltage can also be pulled to ground, and the single power supply voltage range is large, and it also has temperature compensation. It can be widely used in transducer amplifiers, DC gain circuits and other applications.
The LM124 series and its related parts (LM224, LM324, LM2902) are four‑channel, low‑power 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 swing inputs and outputs to ground.
Key data include a supply voltage range of 3 V to 32 V (single) or +1.5 V to +16 V (dual), a unity‑gain bandwidth of 1 MHz, a typical supply current of 700 µA, and low input offset voltage (2 mV). The document also lists absolute maximum ratings, typical performance curves, pin‑out diagrams, and physical dimensions for various package types.
