conversion. The data format is unsigned, binary for unipolar mode, and two’s complement for bipolar mode.
OFFSET CAL Register (Power-On State: 0000 0000 0000 0000 0000
The OFFSET CAL register contains the 24-bit data of
the most recently completed offset calibration.
OFFSET<23:0>: Offset-calibration bits. The data format
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

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.
