Figure 17-10. 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 17-11. 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:

0LSB
