Unipolar/Bipolar (UNI)
The UNI bit determines whether the conversion will be
unipolar or bipolar. When UNI is a logical one, a unipolar
conversion will be performed on the selected input volt-
age. When UNI is a logical zero, a bipolar conversion will
result. The input span and code assignment for each
conversion type are shown in the figures below:
Unipolar Output Code (UNI = 1)
