Calibration Type
0
00A Full Internal Calibration is initiated where the Internal DAC is calibrated
followed by the Internal Gain Error, and finally the Internal Offset Error is
calibrated out. This is the default setting.
0
1
Here the Internal Gain Error is calibrated out followed by the Internal Offset
Error calibrated out.
0
1
0
This calibrates out the Internal Offset Error only.
0
1
This calibrates out the Internal Gain Error only.
1
00A Full System Calibration is initiated here where first the Internal DAC is
calibrated followed by the System Gain Error, and finally the System Offset
Error is calibrated out.
1
0
1
Here the System Gain Error is calibrated out followed by the System Offset
Error.
