Product Details
The AD8271 is a low distortion, precision difference amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier with gains of ½, 1, or 2. It can also be configured in over 40 single-ended configurations, with gains ranging from −2 to +3.
The AD8271 comes in a 10-lead MSOP package. The AD8271 operates on both single and dual supplies and requires only a 2.6 mA maximum supply current. It is specified over the industrial temperature range of −40°C to +85°C and is fully RoHS compliant.
For a dual channel version of the AD8271, see the AD8270 data sheet.
