•

Integral Non-linearity (INL): After adjusting for offset and gain error, the INL is the

maximum deviation of an actual transition compared to an ideal transition for any

code. Ideal value: 0 LSB.

Figure 109. 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 110. 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.
