Figure 23-10. Offset error
 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 1.5LSB below maximum). Ideal value: 0LSB
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
