GENERAL DESCRIPTION  
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 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 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.
