Figure 15-9. Offset Error
Figure 15-10. Gain Error
• Offset: The deviation of the first transition (0x000 to 0x001) compared to the ideal transition
• Gain Error: After adjusting for offset, the Gain Error is found as the deviation of the last
(at 0.5 LSB). Ideal value: 0 LSB.
transition (0x3FE to 0x3FF) compared to the ideal transition (at 1.5 LSB below maximum).
