LM2902QT14-13

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902QT14-13 is an automotive-grade quad operational amplifier manufactured by Diodes Incorporated. It features four independent high-gain amplifiers with internal frequency compensation, designed for single or split power supply operation. The device operates within a supply voltage range of 3V to 36V (single) or ±1.5V to ±18V (dual). Key electrical parameters include a unity gain bandwidth of 700kHz, a typical input offset voltage of 2mV, and a low supply current drain of 700µA at 5V. It is qualified to AEC-Q100 Grade 1 standards and housed in a TSSOP-14 package.
