AD8657 Overview
The AD8657/AD8659 are dual and quad micropower, precision, rail-to-rail input/output amplifiers optimized for low power and wide operating supply voltage range applications. The AD8657/AD8659 operate from 2.7 V to 18 V with a typical quiescent supply current of 18 μA. The devices use the Analog Devices, Inc., patented DigiTrim® trimming technique, which achieves low offset voltage.
