Figure 13-12. Differential Non-linearity (DNL)
Quantization Error: Due to the quantization of the input voltage into a finite number of codes, a range of input
voltages (1 LSB wide) will code to the same value. Always ± 0.5 LSB.
Absolute Accuracy: The maximum deviation of an actual (unadjusted) transition compared to an ideal transition
for any code. This is the compound effect of offset, gain error, differential error, non-linearity, and quantization
error. Ideal value: ± 0.5 LSB.
13.11 ADC Conversion Result
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
IN (see Table 13-2 on page 92) is the voltage on the selected input pin and VCC is the voltage reference.
0x00 represents analog ground, and 0xFF represents the selected reference voltage minus one LSB.
