General Description

The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors.

With no external components, it can be configured as a high performance difference amplifier (G = ½ or 2), inverting amplifier (G = ½ or 2), or noninverting amplifier (G = 1½ or 3).

The AD8273 operates on both single and dual supplies and only requires 2.5 mA maximum supply current for each amplifier.
