Overview
The AD8271ARMZ-RL, produced by Analog Devices Inc., is a precision difference amplifier designed for high-performance applications. It features internal gain setting resistors, allowing it to be configured as a difference amplifier with gains of ½, 1, or 2 without any external components. Additionally, it can be configured in over 40 single-ended configurations with gains ranging from −2 to +3. The amplifier operates on both single and dual supplies, with a maximum supply current of 2.6 mA, and is specified over the industrial temperature range of −40°C to +85°C. It is fully RoHS compliant and comes in a compact 10-lead MSOP package.
