GENERAL DESCRIPTION
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
with gains of 0.5, 1, or 2. It can also be configured in over 40 single-
ended configurations, with gains ranging from 2 to +3.
The AD8270 is the first dual-difference amplifier in the small
4 mm × 4 mm LFCSP. It requires the same board area as a typical
single-difference amplifier. The smaller package allows a 2×
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
requires only 2.5 mA maximum supply current for each ampli-
fier. It is specified over the industrial temperature range of
40°C to +85°C and is fully RoHS compliant.
