Table 16b. Output Data Formats for the Bipolar Input Range
Table 17. SOC Register (Read/Write)
SOC: System Offset Calibration Register
The system offset calibration register is a 24-bit read/write register. The data written/read to/from this register is clocked
in/out MSB (most significant bit) first. This register holds the system offset calibration value. The format is always in
two’s complement binary format. A write to the system-calibration register is allowed. The value written remains valid
until it is either rewritten or until an on-demand system-calibration operation is performed, which overwrites the user-
supplied value.
The system offset calibration value is subtracted from each conversion result provided the NOSYSO bit in the CTRL3
register is set to 0. The system offset calibration value is subtracted from the conversion result after self-calibration
but before system gain correction. The system offset calibration value is also applied prior to the 1x or 2x scale factor
associated with bipolar and unipolar modes.
