• 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.
