POWER SUPPLY ADJUSTMENT
3.3 V TO 4.5 V SUPPLY OPERATION
The AD8207 can operate with a single-supply voltage as low
as 3.3 V to 4.5 V. This mode of operation is achieved by con-
necting the RANGE pin (Pin 4) to the supply (see Figure 26).
It is recommended that an external resistor be placed in series
from the RANGE pin to the supply. This resistor can be a
typical 5 kΩ 1% resistor.

Figure 26. 3.3 V Supply Operation
Note that in this mode of operation, the common-mode range
of the AD8207 is limited to 4 V to +35 V. The output and
reference input ranges are limited to the supply of the part. The
user can have a 4.5 V supply and connect the RANGE pin from
3.3 V to 4.5 V. Alternatively, the user can connect the RANGE
pin as high as 4.5 V, with the supply from 3.3 V to 4.5 V.
4.5 V TO 5.5 V SUPPLY OPERATION
In most applications, the AD8207 operates with a single 5 V
supply. In this mode, the operating input common-mode
range of the AD8207 is rated from 4 V to +65 V. To operate
the device with a 5 V supply (includes 4.5 V to 5.5 V), connect
the RANGE pin (Pin 4) to logic low, or GND, as shown in

Figure 27. 5 V Supply Bidirectional Operation
The output and reference input ranges are limited to the
supply voltage used. With a supply voltage from 4.5 V to 5.5 V,
the RANGE pin (Pin 4) should be connected to GND to achieve
the maximum input common-mode range specification of 4 V
to +65 V.
