Overview
The LM2904WHYDT, produced by STMicroelectronics, is a low-power dual operational amplifier designed for use in automotive and industrial control systems. This device consists of two independent, high-gain operational amplifiers with internal frequency compensation. It operates from a single power supply over a wide range of voltages, making it versatile for various applications. The LM2904WHYDT is characterized by its low power supply current, which is independent of the magnitude of the power supply voltage, and its ability to function over a temperature range of -40°C to +125°C.
