The AD8205 is a high-performance, single-supply difference amplifier with a wide input common mode voltage (CMV) operational range of-2V to 65V, which allows the chip to measure small differential voltages--such as across a shunt resistor--in the presence of high voltages (large CMV).
Nonlinearities in the difference amplifier and A/D sections are suppressed by the feedback action.
