AD8216 High Bandwidth, Bidirectional 65 V Difference Amplifier

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

The AD8216 is a single-supply, difference amplifier ideal for amplifying small differential voltages in the presence of large common-mode voltages. The operating input common-mode voltage range extends from −4 V to +65 V. The typical supply voltage is 5 V. 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.
