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 singleended configurations, with gains ranging from -2 to +3. The AD8270 is the first dual-difference amplifier in the small 4 mm x 4 mm 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.
