ADuC7061. ADC Offset Calibration Register (ADC0OF, ADC1OF)

Question

After calibration Primary / Auxiliary Channel ADC Offset Calibration Register (ADC0OF, ADC1OF) always are read = 0. Both self-offset and zero-scale calibration mode. It is unclear how to correct the values for negative/positive offsets.

Karl.O · Accepted Answer

Chopping already corrects the offset error. That is why the offset calibration register (ADC0OF, ADC1OF) reads as 0 after initiating the calibration since the chopping is enabled.)
