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 = or 2), inverting amplifier (G = or 2), or noninverting
amplifier (G = 1 or 3).
The AD8273 operates on both single and dual supplies and only
requires 2.5 mA maximum supply current for each amplifier. It
is specified over the industrial temperature range of 40°C to
+85°C and is fully RoHS compliant.
