AD8205

The AD8205 is a single-supply difference amplifier for amplifying mall differential voltages in the presence of large commonmode oltages. The operating input common-mode voltage ange extends from −2 V to +65 V. The typical single-supply Mltage is 5 V.

The AD8205 is offered in die and packaged form. The operating emperature range for the die is 25°C higher (up to 150°C) than he packaged part to enable the user to apply the AD8205 in igh temperature applications.

Excellent dc performance over temperature keeps errors in the easurement loop to a minimum. Offset drift is typically less han 15 V/°C, and gain drift is typically below 30 ppm/°C.

The output offset can be adjusted from 0.05 V to 4.8 V with a  V supply by using the V_REF1 and V_REF2 pins. With V_REF1 attached o the V+ pin, and V_REF2 attached to the GND pin, the  utput is set at half scale. Attaching both pins to GND causes he output to be unipolar, starting near ground. Attaching both ins to V+ causes the output to be unipolar starting near V+. ther offsets can be obtained by applying an external voltage to he V_REF1 and V_REF2 pins.
