微功耗,零漂移,真正的轨到轨仪表放大器 Micropower, Zero Drift, True Rail-to-Rail Instrumentation Amplifier
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.
