AD8210
External Referenced Output
Tying both V
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
voltage (see Figure 30).
Note that Pin V
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.

Splitting the Supply
By tying one reference pin to V+ and the other to the GND pin,
the output is set at midsupply 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).
