Overview
The LM2902DT, produced by STMicroelectronics, is a low-power, bipolar operational amplifier (op-amp) designed for automotive and industrial control systems. This device consists of four independent, high-gain operational amplifiers that employ internal frequency compensation. It operates from a single power supply over a wide range of voltages (3 V to 30 V) and can also operate from split power supplies (±1.5 V to ±15 V). The LM2902DT is known for its low-power supply current drain, which is independent of the power supply voltage magnitude.
