(4) Zero scale error
(5) Full scale error
(6) Integral linearity error
(7) Differential linearity error
This shows the difference between the actual measured value of the analog input voltage and the theoretical
value (1/2LSB) when the digital output changes from 0……000 to 0……001. If the actual measured value is
greater than the theoretical value, it shows the difference between the actual measured value of the analog input
voltage and the theoretical value (3/2LSB) when the digital output changes from 0……001 to 0……010.
This shows the difference between the actual measured value of the analog input voltage and the theoretical
value (full scale –3/2LSB) when the digital output changes from 1……110 to 1……111.
This shows the degree to which the conversion characteristics deviate from the ideal linear relationship. It
expresses the maximum value of the difference between the actual measured value and the ideal straight line
when the zero scale error and full scale error are 0.
Although the ideal output width for a given code is 1LSB, this value shows the difference between the actual
measured value and the ideal value of the width when outputting a particular code.
