MAX4043EUB+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4043EUB+ is a dual-channel micropower operational amplifier from the Analog Devices/Maxim Integrated MAX4040–MAX4044 family. It operates on a single +2.4V to +5.5V supply or dual ±1.2V to ±2.75V supplies, consuming only 10µA of supply current per amplifier. The device features rail-to-rail input and output capabilities, a 90kHz gain-bandwidth product, and a low-power shutdown mode that reduces supply current to less than 1µA while forcing outputs into a high-impedance state. It is housed in a space-saving 10-pin µMAX package.
