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 = 锟?frac12; or 2), inverting amplifier (G = 锟?frac12; or 2), or noninverting
amplifier (G = 1锟?frac12; 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 鈭?0掳C to
+85掳C and is fully RoHS compliant.
