AD8236 - Micropower Instrumentation Amplifier

General Description

The AD8236 is the lowest power instrumentation amplifier in the industry.

It has rail-to-rail outputs and can operate on voltages as low as 1.8 V.

Its 40 μA maximum supply current makes it an excellent choice in battery-powered applications.

Key Features

  • Low power: 40 μA supply current (maximum) Low input currents 1 pA input bias current 0.5 pA input offset current High CMRR: 110 dB CMRR, G = 100 Space-saving MSOP Zero input crossover distortion Rail-to-rail input and output Gain set with single resistor Operates from 1.8 V to 5.5 V INPUT COMMON-MODE.
