NOTES:
1. The following condition must not be exceeded: V_DD – 0.2V < AV_DD < V_DD + 0.2V.
2. Conditions: AV_SS = 0V; AV_CC = 4.997V; V_CC = 5.0V.
3. The differential non-linearity (DL_e) is the difference between the actual step width and the ideal step width. (See Figure 24).
4. The ADC is monotonic; there are no missing codes.
5. The integral non-linearity (IL_e) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset error. (See Figure 24).
6. The offset error (OS_e) is the absolute difference between the straight line which fits the actual transfer curve (after removing gain error), and
a straight line which fits the ideal transfer curve. (See Figure 24).
7. Guaranteed by design.
8. To meet Error Specification, analog input voltage must be less than 1V/ms.
