Overview
The LM2904YDT is a dual operational amplifier (op-amp) produced by STMicroelectronics. It is designed for use in automotive and industrial control systems, featuring two independent, high-gain op-amps with internal frequency compensation. This device operates from a single power supply over a wide voltage range, making it versatile for various applications. The low power supply drain is independent of the magnitude of the power supply voltage, which is beneficial for energy-efficient designs.
