NOTES:
1. All voltages are referenced to ground.
2. Resistor inputs cannot exceed the substrate bias voltage, V
B
, in the negative direction.
3. INL is used to determine wiper voltage versus expected voltage as determined by wiper position.
4. DNL is used to determine the change in voltage between successive tap positions.
