Nonlinearity error
Nonlinearity error is the deviation between actual and the best-fitting A/D conversion charac-
teristics (see
Bisector characteristic is obtained drawing a line from 1/2 LSB before the first step of the
real characteristic, and 1/2 LSB after the last step again of the real characteristic.
Total unadjusted error
The total unadjusted error (TUE) specifies the maximum deviation from the ideal character-
istic: The number provided in the datasheet represents the maximum error with respect to
the entire characteristic. It is a combination of the offset, gain and integral linearity errors.
The different errors may compensate each other depending on the relative sign of the offset
and gain errors. Refer to

Differential nonlinearity error is the actual step dimension versus the ideal one (1
LSB
Integral nonlinearity error is the distance between the center of the actual step and
the center of the bisector line, in the actual characteristics. Note that for integral
nonlinearity error, the effect of offset, gain and quantization errors is not included.
