NOTES:
1. Conditions: V
SS
= 0 V; V
DD
= 5.12 V.
2. The A/D is monotonic, there are no missing codes
3. The differential non-linearity (DL
e
) is the difference between the actual step width and the ideal step width. See Figure 40.
4. 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 errors. See Figure 40.
5. The offset error (OS
e
) is the absolute difference between the straight line which fits the actual transfer curve (after removing gain error), and
the straight line which fits the ideal transfer curve. See Figure 40.
6. The gain error (G
e
) is the relative difference in percent between the straight line fitting the actual transfer curve (after removing offset error),
and the straight line which fits the ideal transfer curve. Gain error is constant at every point on the transfer curve. See Figure 40.
7. The absolute voltage error (A
) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve.
8. This should be considered when both analog and digital signals are input simultaneously to A/D pins.
9. Changing the input voltage faster than this may cause erroneous readings.
10.A source impedance higher than this driving an A/D input may result in loss of precision and erroneous readings.
