Overview
The LM2902KAVQPWREP is a quad operational amplifier produced by Texas Instruments. This device consists of four independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. It is also capable of operating from split power supplies. The LM2902 is particularly suited for automotive and industrial control systems due to its extended temperature performance and low power supply current drain, which is independent of the supply voltage magnitude.
