NOTES:
1. Integral nonlinearity refers to the deviation of each individual code from a line drawn from zero to full scale. The point used as zero
occurs 1/2 LSB before the first code transition. The full–scale point is defined as a level 1/2 LSB beyond the last code transition.
The deviation is measured from the center of each particular code to the true straight line between these two endpoints.
2. An ideal ADC exhibits code transitions that are exactly 1 LSB apart. DNL is the deviation from this ideal value. Therefore this measure
indicates how uniform the transfer function step sizes are. The ideal step size is defined here as the step size for the device under
test (i.e., (last transition level – first transition level)
÷
(2n – 2)). Using this definition for DNL separates the effects of gain and offset
error. A minimum DNL better than –1 LSB ensures no missing codes.
3. Zero error is defined as the difference in analog input voltage – between the ideal voltage and the actual voltage – that will switch
the ADC output from code 0 to code 1. The ideal voltage level is determined by adding the voltage corresponding to 1/2 LSB to the
bottom reference level. The voltage corresponding to 1 LSB is found from the difference of top and bottom references divided by
the number of ADC output levels (256).
Full-scale error is defined as the difference in analog input voltage – between the ideal voltage and the actual voltage – that will switch
the ADC output from code 254 to code 255. The ideal voltage level is determined by subtracting the voltage corresponding to 1.5
LSB from the top reference level. The voltage corresponding to 1 LSB is found from the difference of top and bottom references
divided by the number of ADC output levels (256).
