GENERAL DESCRIPTION

The AD8237 is a micropower, zero drift, rail-to-rail input and output instrumentation amplifier. The relative match of two resistors sets any gain from 1 to 1000. The AD8237 has excellent gain accuracy performance that can be preserved at any gain with two ratio-matched resistors.

The AD8237 employs the indirect current feedback architecture to achieve a true rail-to-rail capability. Unlike conventional in-amps, the AD8237 can fully amplify signals with common-mode voltage at or even slightly beyond its supplies. This enables applications with high common-mode voltages to use smaller supplies and save power.

The AD8237 is an excellent choice for portable systems. With a minimum supply voltage of 1.8 V, a 115 μA typical supply current, and wide input range, the AD8237 makes full use of a limited power budget, yet offers bandwidth and drift performance suitable for bench-top systems.
