GENERAL DESCRIPTION
The AD8210 is a single-supply, difference amplifier ideal 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. e typical supply
voltage is 5 V.
The AD8210 is offered in a SOIC package. The operating
temperature range is −40°C to +125°C.
Excellent ac and dc performance over temperature keep errors
in the measurement loop to a minimum. Offset drift and gain
drift are guaranteed to a maximum of 8 μV/°C and 20 ppm/°C,
respectively.
The output offset can be adjusted from 0.05 V to 4.9 V with
a 5 V supply by using the V
REF
1 pin and the V
REF
2 pin. With the
V
REF
1 pin attached to the V+ pin and the V
REF
2 pin attached to
the GND pin, the output is set at half scale. Attaching both V
REF
1
and V
REF
2 to GND causes the output to be unipolar, starting
near ground. Attaching both V
REF
1 and V
REF
2 to V+ causes the
output to be unipolar, starting near V+. Other offsets can be
obtained by applying an external voltage to V
REF
1 and V
REF
2.
