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.

The AD8236’s high input impedance, low input bias current of

1 pA, high CMRR of 110 dB (G = 100), small size, and low power

offer tremendous value. It has a wider common-mode voltage

range than typical three-op-amp instrumentation amplifiers,

making this a great solution for applications that operate on a

single 1.8 V or 3 V supply. An innovative input stage allows for

a wide rail-to-rail input voltage range without the crossover

distortion common in other designs.
