• Gain Error: After adjusting for offset, the Gain Error is found as the deviation of the last transition (0xFE to 0xFF)
compared to the ideal transition (at 1.5 LSB below maximum). Ideal value: 0 LSB
Figure 13-10. 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.

• 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.
