3.5 Output Coding Format
The reference voltage directly defines the input voltage range in both the unipolar and bipolar configura-
tions. In the unipolar configuration (BP/UP low), the first code transition occurs 0.5 LSB above zero, and
the final code transition occurs 1.5 LSBs below VREF. In the bipolar configuration (BP/UP high), the first
code transition occurs 0.5 LSB above -VREF and the last transition occurs 1.5 LSBs below +VREF. See
Table 1 for the output coding of the converter.
