Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 7 pF). A high Cparasitic value will downgrade conversion accuracy. To remedy
this, fADC should be reduced.

(1) Example of an actual transfer curve
(2) The ideal transfer curve
(3) End point correlation line
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.
EG=Gain Error: deviation between the last ideal
transition and the last actual one.
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.
