Differential Non-linearity (DNL): The maximum deviation of the actual code width (the interval
between two adjacent transitions) from the ideal code width (1 LSB). Ideal value: 0 LSB.
Figure 16-12. 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
16.11 ADC Conversion Result
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
where V
IN is the voltage on the selected input pin and VREF the selected voltage reference (see
Table 16-3 on page 128 and Table 16-4 on page 129). 0x000 represents analog ground, and
0x3FF represents the selected reference voltage minus one LSB. The result is presented in one-
sided form, from 0x3FF to 0x000.
16.12 Temperature Measurement
The temperature measurement is based on an on-chip temperature sensor that is coupled to a
single ended ADC channel. Selecting the ADC4 channel by writing the MUX[2:0] bits in ADMUX
register to “111” enables the temperature sensor. The internal 1.1V reference must also be
selected for the ADC reference source in the temperature sensor measurement. When the tem-
