The offset self-calibration command corrects offset errors internal to the ADC. When the offset self-calibration command is sent, the ADC disconnects the external inputs, shorts the inputs to the PGA, and then averages 16 conversion results to compute the calibration value. Averaging the data reduces conversion noise to improve calibration accuracy. When calibration is complete, the ADC restores the user input and performs one conversion using the new calibration value.
