The AD8270 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=0.5, 1, or 2), inverting amplifier (G=0.5, 1, or 2) or non-
inverting amplifier (G=1.5, 2, or 3).

The AD8270 is the first dual difference amplifier in the small 4
mm × 4mm LFCSP. It requires the same board area as a typical
single difference amplifier. The smaller package allows a 2X
increase in channel density and a lower cost per channel, all
with no compromise in performance.
The AD8270 operates on both single and dual supplies and only
requires 2.5 mA maximum supply current for both amplifiers. It
is specified over the industrial temperature range of 40°C to
+85°C and is fully RoHS compliant.
