CAP OFFSET CALIBRATION REGISTER
16 Bits, Address Pointer 0x0D, 0x0E,
Default Value 0x8000
The capacitive offset calibration register holds the capacitive
channel zero-scale calibration coefficient. The coefficient is
used to digitally remove the capacitive channel offset. The
register value is updated automatically following the execution
of a capacitance offset calibration. The capacitive offset calibra-
tion resolution (cap offset register LSB) is less than 32 aF; the
full range is ±1 pF.
CAP GAIN CALIBRATION REGISTER
16 Bits, Address Pointer 0x0F, 0x10,
Default Value 0xXXXX
Capacitive gain calibration register. The register holds the
capacitive channel full-scale factory calibration coefficient.
VOLT GAIN CALIBRATION REGISTER
16 Bits, Address Pointer 0x11,0x12,
Default Value 0xXXXX
Voltage gain calibration register. The register holds the voltage
channel full-scale factory calibration coefficient.
