well as selections of offset calibration channels. MUX0 bit works as a gain selection bit for differ-
ential channels shown in
selected and when it is set (‘1’) 20x gain is selected. For normal differential channel pairs MUX5
bit work as a polarity reversal bit. Togling of the MUX5 bit exhanges the positive and negative
channel other way a round.
For offset calibration purpose the offset of the certain differential channels can be measure by
selecting the same input for both negative and positive input. This calibration can be done for
ADC0, ADC3 and ADC7.
