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. The typical supply
voltage is 5 V.
The AD8210 is offered in a SOIC package. The operating
temperature range is 40癈 to +125癈.
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 糣/癈 and 20 ppm/癈,
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
VREF1 pin attached to the V+ pin and the VREF2 pin attached to
the GND pin, the output is set at half scale. Attaching both VREF1
and VREF2 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
