ADC Conversion Result
Figure 22-12. Integral Non-linearity (INL)
Figure 22-13. Differential Non-linearity (DNL)
After the conversion is complete (ADIF is high), the conversion result can be found in the ADC
Result Registers (ADCL, ADCH).
For single ended conversion, the result is

represents the selected reference voltage minus one LSB.
• Differential Non-linearity (DNL): The maximum deviation of the actual code width (the interval
• Quantization Error: Due to the quantization of the input voltage into a finite number of codes,
• Absolute Accuracy: The maximum deviation of an actual (unadjusted) transition compared to
between two adjacent transitions) from the ideal code width (1 LSB). Ideal value: 0 LSB.
