• Gain Error: After adjusting for offset, the Gain Error is found as the deviation of the last transition (0x3FE to
0x3FF) compared to the ideal transition (at 1.5 LSB below maximum). Ideal value: 0 LSB
Figure 23-11. 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
