[1] Conditions: VSSA = 0 V, VDDA = 3.3 V.
[2] The ADC is monotonic, there are no missing codes.
[3] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 21.
[4] The integral non-linearity (EL(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 21.
[5] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 21.
[6] The gain error (EG) 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 21.
[7] The absolute error (ET) 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 21.
[8] See Figure 22.
