The AD8206 is a single-supply difference amplifier for amplifying small differential voltages in the presence of large common-mode voltages. The operating input common-mode voltage range extends from -2 V to +65 V. The typical single-supply voltage is 5 V.
The AD8206 is offered in an 8-lead SOIC package and it is rated throughout the automotive temperature range of −40°C to +125°C.
Excellent DC performance over temperature keeps errors in the measurement loop to a minimum. Offset drift is typically less than 15 µV/°C, and gain drift is typically below 30 ppm/°C.
The output offset can be adjusted from 0.08 V to 4.7 V with a 5 V supply by using the VREF1 and VREF2 pins. With VREF1 attached to the V+ pin, and VREF2 attached to the GND pin, the output is set at half scale. Attaching both pins to GND causes the output to be unipolar, starting near ground. Attaching both pins to V+ causes the output to be unipolar starting near V+. Other offsets can be obtained by applying an external voltage to the VREF1 and VREF2 pins.
