GENERAL DESCRIPTION

Table 1. Difference Amplifiers by Category

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.

It is specified over the industrial temperature range of −40°C to

+85°C and is fully RoHS compliant.
