EXTERNAL REFERENCED OUTPUT
Tying both pins together and to a reference produces an output
equal to the reference voltage when there is no differential input
(see Figure 19). The output moves down from the reference
voltage when the input is negative, relative to the IN pin and
up when the input is positive, relative to the IN pin.

SPLITTING THE SUPPLY
By tying one reference pin to V+ and the other to the ground
pin, the output is set at half of the supply when there is no
differential input (see Figure 20). The benefit is that no external
reference is required to offset the output for bidirectional
current measurement. This creates a midscale offset that is
ratiometric to the supply, which means that if the supply increases
or decreases, the output remains at half the supply. 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 goes to 2.75 V.

SPLITTING AN EXTERNAL REFERENCE
In this case, an external reference is divided by 2 with an
accuracy of approximately 0.5% by connecting one VREF pin to
