Overview
The LM2902YPT is a low-power, quad operational amplifier (op-amp) produced by STMicroelectronics. This device consists of four independent, high-gain operational amplifiers that employ internal frequency compensation. It is specifically designed for automotive and industrial control systems, offering a wide range of operational capabilities.
The LM2902YPT operates from a single power supply over a wide voltage range (3 V to 30 V) and can also operate from split power supplies (±1.5 V to ±15 V). It features low power supply current drain, which is independent of the power supply voltage magnitude.
