Excellent ac and dc performance 10 µV/°C offset drift 10 ppm/°C gain drift Qualified for automotive applications APPLICATIONS High-side current sensing in DC-to-dc converters Motor controls Transmission controls Diesel-injection controls Engine management Suspension controls Vehicle dynamic controls GENERAL DESCRIPTION
The AD8216 is a single-supply, difference amplifier ideal for Excellent ac and dc performance over temperature keep errors amplifying small differential voltages in the presence of large in the measurement loop to a minimum. Offset and gain drift common-mode voltages. The operating input common-mode are guaranteed to a maximum of 20 µV/°C and 15 ppm/°C, voltage range extends from −4 V to +65 V. The typical supply respectively. voltage is 5 V. The AD8216 features a 3 MHz bandwidth, allowing for the input-to-output propagation delay that is The output offset can be adjusted from 0.06 V to 4.9 V with a always less than 150 ns. This feature is ideal for applications 5 V supply by using the VREF1 pin and the VREF2 pin. With the monitoring rapidly increasing and decreasing load currents. 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 The AD8216 is offered in a SOIC package. The operating and VREF2 to GND causes the output to be unipolar, starting temperature range is −40°C to +125°C. 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.
