LM2902M

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902M is a quad low-power operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC package. It features a gain-bandwidth product of 1 MHz and a slew rate of 1.5 V/us. The device operates on a single supply voltage ranging from 3 V to 26 V or dual supplies from ±1.5 V to ±13 V. Key electrical specifications include an input offset voltage of 7 mV, input bias current of 250 nA, and a typical quiescent current of 1.5 mA per channel. It provides an output current capability of 40 mA and supports operation within a temperature range of -40°C to +85°C.
