Overview
The LM2904WHYST is a dual general-purpose operational amplifier produced by STMicroelectronics. This component is designed for use in automotive and industrial control systems, offering high-gain and internally implemented frequency compensation. It 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, and the input common-mode voltage range includes ground, allowing the output voltage to swing to ground even in single-power supply systems.
