Analog Devices AD8212 High Voltage Current Shunt Monitor Data Sheet
The AD8212 is a high common-mode voltage current shunt monitor that accurately amplifies small differential input voltages in the presence of large common-mode voltages up to 65 V, or greater than 500 V with an external pass transistor. It features an integrated 5 V series regulator and an adjustable gain set by an external resistor, making it ideal for current monitoring across shunt resistors in applications controlling loads like motors and solenoids.
The device operates with a supply voltage range of 7 V to 65 V in normal mode, with a typical common-mode voltage range of 7 V to 65 V. For high-voltage applications, an external PNP transistor extends the common-mode range to over 500 V. The output current is proportional to the input differential voltage and can be converted to a voltage using an external resistor.
