MAX4194ESA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4194ESA+T is a micropower, single-supply, rail-to-rail precision instrumentation amplifier in an 8-pin SO package. It operates from +2.7V to +7.5V single supplies or ±1.35V to ±3.75V dual supplies with a typical quiescent current of 93µA. The device features variable gain set by an external resistor between +1V/V and +10,000V/V using the formula G = 1 + (50kΩ/RG). Key electrical specifications include a maximum input offset voltage of ±100µV at G=+1V/V, a -3dB bandwidth of 250kHz at unity gain, and a DC common-mode rejection ratio of up to 115dB.
