LPC1769/68/67/66/65/64/63

32-bit ARM Cortex-M3 microcontroller

[1]

The ADC is monotonic, there are no missing codes.

[2]

The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 26.

[3]

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 26.

[4]

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 26.

[5]

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 26.

[6]

The conversion frequency corresponds to the number of samples per second.
