GENERAL DESCRIPTION
The AD8274 is a difference amplifier that delivers excellent ac and dc performance. Built on Analog Devices, Inc., proprietary iPolar® process and laser-trimmed resistors, AD8274 achieves a breakthrough in distortion vs. current consumption and has excellent gain drift, gain accuracy, and CMRR.
Distortion in the audio band is an extremely low 0.00025% (112 dB) at a gain of ½ and 0.
