A
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.
Here the
Internal Gain Error
is calibrated out followed by the
Internal Offset
Error
calibrated out.
This calibrates out the
Internal Offset Error
only.
This calibrates out the
Internal Gain Error
only.
A
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.
Here the
System Gain Error
is calibrated out followed by the
System Offset
Error
.
This calibrates out the
System Offset Error
only.
This calibrates out the
System Gain Error
only.
