AD8210
External Referenced Output
Tying both V
REF
pins together to an external reference produces
an output offset at the reference voltage when there is no
differential input (see Figure 29). When the input is negative
relative to the IN pin, the output moves down from the
reference voltage. When the input is positive relative to the
IN pin, the output increases.

Splitting an External Reference
In this case, an external reference is divided by two with
an accuracy of approximately 0.2% by connecting one
V
REF
pin to ground and the other V
REF
pin to the reference
voltage (see Figure 30).
Note that Pin V
REF
1 and Pin V
REF
2 are tied to internal precision
resistors that connect to an internal offset node. There is no
operational difference between the pins.
For proper operation, the AD8210 output offset should not be
set with a resistor voltage divider. Any additional external
resistance could create a gain error. A low impedance voltage
source should be used to set the output offset of the AD8210.

Figure 30. Split External Reference
Splitting the Supply
By tying one reference pin to V+ and the other to the GND pin,
the output is set at mid supply when there is no differential
input (see Figure 31). This mode is beneficial because no
external reference is required to offset the output for
bidirectional current measurement. This creates a midscale
offset that is ratiometric to the supply, meaning that if the
supply increases or decreases, the output still remains at half
scale. For example, if the supply is 5.0 V, the output is at half
scale or 2.5 V. If the supply increases by 10% (to 5.5 V), the
output also increases by 10% (2.75 V).
