ADuC7061. ADC Offset Calibration Register (ADC0OF, ADC1OF)

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.

  • Hi,

    I saw that you attached an image, but it's not loading on my end.

    Have you checked the offset calibration register before initiating the calibration? Is the reading 0 as well?

    The ADC offset calibration register is automatically applied to the ADC reading to compensate for the offset error.

    Regards,
