13.11 ADC Conversion Result
8127E–AVR–11/11
Figure 13-12. Differential Non-linearity (DNL)
After the conversion is complete (ADIF is high), the conversion result can be found in the ADC
Data Register (ADCL). For single ended conversion, the result is
where V
voltage reference. 0x00 represents analog ground, and 0xFF 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.
a range of input voltages (1 LSB wide) will code to the same value. Always ± 0.5 LSB.

error, non-linearity, and quantization error. Ideal value: ± 0.5 LSB.
