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 0.00035% (109 dB) at a gain of 2 while driving a 600 Ω load With supply voltages up to ±18 V (+36 V single supply), the AD8274 is well suited for measuring large industrial signals. Additionally, the part’s resistor divider architecture allows it to measure voltages beyond the supplies.
