GENERAL DESCRIPTION  
Table 1. Difference Amplifiers by Category  
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.
