GENERAL DESCRIPTION
The AD8205 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 AD8205 is offered in an 8-lead SOIC package and rated for
operation from 40°C to +125°C for the Y and W grade
models. The H grade version of the AD8205 is rated from
40°C to +150°C.
Excellent dc performance over temperature keeps errors in the
measurement loop to a minimum. Offset drift is typically less
than 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
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.
