The offset calibration command corrects offset errors. To calibrate offset errors, short the inputs to the ADC or to calibrate the system, short the signal inputs to the system. When the command is sent, the ADC averages 16 conversion results to reduce conversion noise for improved calibration accuracy. When calibration is complete, the ADC performs one conversion using the new calibration value. The new calibration value is written to the offset calibration register.
