LM2902D

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902D is a quad low-power operational amplifier manufactured by Texas Instruments. It features four independent, high-gain, internally frequency-compensated amplifiers designed for single or split power supply operation. Key electrical parameters include a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/us. The input offset voltage is typically 7 mV with an input bias current of 250 nA. It operates on a single supply voltage ranging from 3 V to 26 V, or dual supplies up to ±13 V. The device draws a typical operating supply current of 1.4 mA per channel and provides an output current capability of 20 mA. Common mode rejection ratio is specified at 80 dB, and input voltage noise density is 35 nV/sqrt Hz.
