Figure 21-12. Integral Non-linearity (INL)

• 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 21-13. 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.
