36.2.1 Offset Calibration
The Operational Amplifier Calibration Source Select (OFCSEL) bits are used to select from the following calibration sources:
- Factory-Calibration data
- Self-Calibration data
- User-defined Calibration data
Important: The OPA input offset voltage is factory-calibrated and any data written to
the OPAxOFFSET
register will adjust the input offset voltage from the factory-calibrated value. The factory
calibrated input offset voltage will be restored on a Reset event, overwriting any previous
data that may have been written to the register.
