Analog Devices AD8205 Data Sheet
The AD8205 is a single‑supply difference amplifier designed for high‑side current‑sense applications. It offers a wide common‑mode voltage range (‑2 V to +65 V), a fixed gain of 50 V/V, and excellent AC/DC performance with low offset drift and high CMRR.
Typical uses include motor‑control current sensing, diesel‑injection control, and H‑bridge motor control. The device can be configured for unidirectional, ground‑referenced, V+‑referenced, or bidirectional operation by adjusting the VREF pins, and automotive‑qualified versions are available.
