Figure 24-10. Offset Error
Figure 24-11. Gain Error
• 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
transition (0x3FE to 0x3FF) compared to the ideal transition (at 1.5 LSB below maximum).
Ideal value: 0 LSB
deviation of an actual transition compared to an ideal transition for any code. Ideal value: 0
