Bits 15:8
Offset Value. The input offset of the I-Channel
ADC is adjusted linearly and monotonically by
the value in this field. 00h provides a nominal
zero offset, while FFh provides a nominal 45
mV of offset. Thus, each code step provides
0.176 mV of offset.
POR State: 0000 0000 b
Bit 7
Sign bit. 0b gives positive offset, 1b gives
negative offset.

Full Scale Voltage Adjust Value. The input full-
scale voltage or gain of the I-Channel ADC is
adjusted linearly and monotonically with a 9 bit
data value. The adjustment range is ±20% of
the nominal 700 mV
P-P differential value.

For best performance, it is recommended that
the value in this field be limited to the range of
0110 0000 0b to 1110 0000 0b. i.e., limit the
amount of adjustment to ±15%. The remaining
±5% headroom allows for the ADC's own full
scale variation. A gain adjustment does not
require ADC re-calibration.
