on robust pins is specified in Section 3.3.5.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in Section 3.3.5 does not
affect the ADC accuracy.
2.
Calibration is needed once after each power-up.

(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.
