Vin (LSBIDEAL)

(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 ide-

al 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.
