LM2902KD

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902KD is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It features a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/us. The device operates on a single supply voltage ranging from 3 V to 32 V or dual supplies from ±1.5 V to ±16 V. Key electrical specifications include an input offset voltage of 7 mV, input bias current of 250 nA, and a typical quiescent current of 1.4 mA for all four channels. It supports an output current of 20 mA per channel with a common-mode rejection ratio of 80 dB.
