ADC conversion accuracy

Figure 16. ADC conversion accuracy

ADC accuracy parameter definitions:



ET = total unadjusted error: Maximum deviation between the actual and the ideal

transfer curves.



EO = offset error: deviation between the first actual transition and the first ideal one.



EOG = offset + gain error (1-point gain): deviation between the last ideal transition and

the last actual one.



EG = gain error (2-point gain): defined so that EOG = EO + EG (parameter correlated to

the deviation of the characteristic slope).



ED = differential linearity error: maximum deviation between actual steps and the ideal

one.



EL = integral linearity error: maximum deviation between any actual transition and the

end point correlation line.
