Non-linearity error
Non-Linearity error is the deviation between actual and the best-fitting A/D conversion
characteristics (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 specifies the maximum deviation from the ideal characteristic:
the number provided in the Data Sheet 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
Figure 42. A/D conversion characteristic

(HEX)
Differential Non-Linearity error is the actual step dimension versus the ideal one (1
LSB
Integral Non-Linearity 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 Non-
Linearity error, the effect of offset, gain and quantization errors is not included.
