Figure 16-11. Integral Non-linearity (INL)
• Offset: The deviation of the first transition (0x000 to 0x001) compared to the ideal transition
• Gain Error: After adjusting for offset, the Gain Error is found as the deviation of the last
• 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
