Differential Non-linearity (DNL): The maximum deviation of the actual code width (the
interval between two adjacent transitions) from the ideal code width (1LSB). Ideal value:
0LSB.
Quantization Error: Due to the quantization of the input voltage into a finite number of codes,
a range of input voltages (1LSB wide) will code to the same value. Always ±0.5LSB.
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: ±0.5LSB.
