The AD8212 is a high common-mode voltage, current shunt monitor. It accurately amplifies a small differential input voltage in the presence of large common-mode voltages up to 65 V (>500 V with an external PNP transistor).The AD8212 is ideal for current monitoring across a shunt resistor in applications controlling loads, such as motors and solenoids. The current output of the device is proportional to the input differential voltage. The user can select an external resistor to set the desired gain. The typical common-mode voltage range of the AD8212 is 7 V to 65 V.Another feature of the AD8212 is high voltage operation, which is achieved by using an external high voltage breakdown PNP transistor. In this configuration, the common-mode range of the AD8212 is equal to the breakdown of the external PNP transistor. Therefore, operation at several hundred volts is easily achieved.The AD8212 features a patented output base current compensation circuit for high voltage operation mode.

The AD8216 features a 3 MHz bandwidth, allowing for the input-to-output propagation delay that is always less than 150 ns. This feature is ideal for applications monitoring rapidly increasing and decreasing load currents.The AD8216 is offered in a SOIC package. The operating temperature range is −40°C to +125°C.Excellent ac and dc performance over temperature keep errors in the measurement loop to a minimum. Offset and gain drift are guaranteed to a maximum of 20 μV/°C and 15 ppm/°C, respectively.The output offset can be adjusted from 0.06 V to 4.9 V with a 5 V supply by using the VREF1 pin and the VREF2 pin. With the VREF1 pin attached to the V+ pin and the VREF2 pin attached to the GND pin, the output is set at half scale. Attaching both VREF1 and VREF2 to GND causes the output to be unipolar, starting near ground. Attaching both VREF1 and VREF2 to V+ causes the output to be unipolar, starting near V+. Other offsets can be obtained by applying an external voltage to VREF1 and VREF2.Applications High-side current sensing in DC-to-dc converters Motor controls Transmission controls Diesel-injection controls Engine management Suspension controls Vehicle dynamic controls
