The AD8270 is the first dual difference amplifier in the small 4 mm x 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 -40C to +85C and is fully RoHS compliant.
