Analog Devices AD8212 Product Handbook
The AD8212 is a high‑common‑mode voltage current shunt monitor that accurately amplifies a small differential input voltage in the presence of large common‑mode voltages. It offers adjustable gain, an integrated 5 V series regulator, and can operate from 7 V to 65 V normally, or above 500 V when used with an external PNP transistor.
The handbook provides full electrical specifications, absolute maximum ratings, pin descriptions, typical performance curves, and guidance on high‑voltage operation, making it a comprehensive reference for designers of motor controls, power supplies, battery monitors, and other current‑sensing applications.
