Figure 19-10. Gain Error

• 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 19-11. 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.
