Overview
The AD8206YRZ from Analog Devices Inc. is a high common-mode voltage, bidirectional current shunt amplifier designed for amplifying small differential voltages in the presence of large common-mode voltages. This single-supply difference amplifier is notable for its excellent DC performance over temperature, minimizing errors in the measurement loop. It features low offset drift (typically less than 15µV/°C) and low gain drift (typically below 30ppm/°C), making it highly accurate and reliable across various temperature ranges.
