The OFFSET CAL register contains the 24-bit data of
the most recently completed offset calibration.
is two’s complement and is subtracted from the ADC
output before being written to the DATA register. The
offset calibration allows input offset errors between

ADC<15:0> Analog-to-digital conversion data bits. These 16 bits are the results from the most recently completed
conversion. The data format is unsigned, binary for unipolar mode, and two’s complement for bipolar mode.

or self offset calibration. Self-calibration performs a cali-
bration for the entire signal path. See the ADC
Calibration section for more details.
The ADC input voltage range specifications must
always be obeyed and the OFFSET CAL register effec-
tively offsets the ADC digital scale to a “zero” value
determined by the calibration.
