GENERAL DESCRIPTION
The AD8205 is a single-supply difference amplifier for amplify-
ing 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 AD8205 is offered in die and packaged form. The operating
temperature range for the die is 25°C higher (up to 150°C) than
the packaged part to enable the user to apply the AD8205 in
high temperature applications.
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 0.05 V to 4.8 V with a
5 V supply by using the V
REF
1 and V
REF
2 pins. With V
REF
1 at-
tached to the V+ pin, and V
REF
2 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 V
REF
1 and V
REF
2 pins.
