Figure 24-13. Integral Non-linearity (INL)
• Integral Non-linearity (INL): After adjusting for offset and gain error, the INL is the maximum
• Differential Non-linearity (DNL): The maximum deviation of the actual code width (the interval
deviation of an actual transition compared to an ideal transition for any code. Ideal value: 0
