it can be configured as a high performance difference amplifier AD8270 AD628 AD8202 AD8205 with gains of ½, 1, or 2. It can also be configured in over 40 single- AD8273 AD629 AD8203 AD8206 ended configurations, with gains ranging from −2 to +3. AD8274 AD8216 The AD8271 comes in a 10-lead MSOP package. The AD8271 AMP03 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.
