Overview
The LM2904ST, produced by STMicroelectronics, is a dual operational amplifier designed for low power consumption and high performance in various applications. This device consists of two independent, high gain operational amplifiers with internal frequency compensation. It is particularly suited for automotive and industrial control systems due to its robust specifications and wide operating voltage range.
The LM2904ST operates from a single power supply over a wide range of voltages (3V to 30V), making it versatile for different system requirements. Its low power supply drain is independent of the magnitude of the power supply voltage, which is beneficial for power-efficient designs.
