ET=Total Unadjusted Error: maximum devi-

ation 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 ide-

al one.

EL=Integral Linearity Error: maximum devi-

ation between any actual transition and the

end point correlation line.
