GENERAL DESCRIPTION

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.

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 V_REF1 and V_REF2 pins. With V_REF

The AD8206 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 AD8206 in

high temperature applications.

attached to the V+ pin, and V_REF2 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_REF1 and V_REF2 pins.
