= 0 V on pin ADC10B_GNDA, V
DD(ADC)
=3.3V.
[3] 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 10.
[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 10
.
