24-Bit Multi-Channel Low-Power
1.9ksps Delta-Sigma ADC with PGA
SELF_OFF (0x17)
The self-calibration offset value is subtracted from the conversion result, provided that the NOSELFOC bit is set to 0.
The format is always 2’s complement binary format, and is unaffected by the U_BN and FORMAT bits. Writing to the
self-calibration register is allowed. The value remains valid until either a new write is completed or an on-demand self-
calibration operation is performed, which will overwrite the current value.
The self-calibration offset value is subtracted from the conversion result before the self-calibration gain correction and
before the system offset and gain correction. It is also applied prior to the 2x scale factor associated with unipolar mode.
