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 VREF1 and VREF2 pins. With VREF1 attached o the V+ pin, and VREF2 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 VREF1 and VREF2 pins.
