MAX4162ESA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4162ESA+T is a single-channel micropower operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from 2.5V to 10V or dual supplies of ±1.25V to ±5V. The device features true rail-to-rail inputs and outputs, with an input common-mode voltage range extending 250mV beyond either supply rail. Key electrical parameters include a gain-bandwidth product of 200kHz, a quiescent current of 25µA per amplifier, and a typical input bias current of 1.0pA. It is unity-gain stable and capable of driving any capacitive load while maintaining stability.
