DD(3V3)
= 3.3 V.
The ADC is monotonic, there are no missing codes.

[4]
The differential linearity error (E
D
) is the difference between the actual step width and the ideal step width.
See
Figure 18
.
[5]
The integral non-linearity (E
L(adj)
) 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 18
.
[6]
The offset error (E
O
) is the absolute difference between the straight line which fits the actual curve and the
straight line which fits the ideal curve. See
Figure 18
.
[7]
The gain error (E
G
) 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. See
Figure 18
.
[8]
The absolute error (E
T
) 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. See
Figure 18
.
