... The operating input common-mode voltage range extends from − +65 V. The typical supply voltage 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 a single-supply difference amplifier typically used to accurately amplify a small differential current shunt voltage in the presence of a rapidly changing common-mode voltage. The AD8216 consists of an amplifier (A1), a resistor network, a small voltage reference, and a bias circuit (not shown), see Figure 23. ...

... Data Sheet OUTPUT OFFSET ADJUSTMENT The output of the AD8216 can be adjusted for unidirectional or bidirectional operation. UNIDIRECTIONAL OPERATION Unidirectional operation allows the AD8216 to measure currents through a resistive shunt in one direction. The basic modes for unidirectional operation are ground referenced output mode and V+ referenced output mode. ...

... Another typical application for the AD8216 is as part of the control loop in H-bridge motor controls. In this case, the AD8216 is placed in the middle of the H-bridge so that it can accurately measure current in both directions by using the shunt available at the motor (see Figure 31) ...
