Two channels in small 4 mm × 4 mm LFCSP
Supply current: 2.5 mA per channel
Supply range: ±2.5 V to ±18 V

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 amplifier. It is specified over the industrial temperature range of −40°C to +85°C and is fully RoHS compliant.
