Overview
The LM2904WYDT is a low-power dual operational amplifier produced by STMicroelectronics. This device is specifically designed for automotive and industrial control systems. It consists of two independent, high-gain operational amplifiers with internal frequency compensation. The LM2904WYDT operates from a single power supply over a wide voltage range of 3V to 30V, 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 power-efficient designs.
