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.
