AD8237ARMZ Description
The AD8237ARMZ is a rail-to-rail input and output instrumentation amplifier with micropower and zero drift. Any gain from 1 to 1000 is set by the relative match of two resistors. With two ratio-matched resistors, the AD8237 provides exceptional gain accuracy that can be maintained at any gain.
To provide real rail-to-rail capability, the AD8237ARMZ uses an indirect current feedback architecture. The AD8237ARMZ, unlike traditional in-amps, can fully amplify signals with common-mode voltage at or slightly over its supply. This allows high common-mode voltage applications to use a smaller power supply and conserve energy. For portable systems, the AD8237ARMZ is a suitable choice. The AD8237ARMZ makes full use of a restricted power budget, offering bandwidth and drift performance ideal for bench-top systems, with a minimum supply voltage of 1.8 V, a typical supply current of 115 A, and a wide input range.
