LM2902 Overview
This circuit consists of four independent, high-gain operational amplifiers (op amps) which employ internal frequency pensation and are specifically designed for automotive and industrial control systems. The device operates from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low-power supply current drain is independent from the power supply voltage magnitude.
