(5) Full-scale error
This shows the difference between the actual measurement value of the analog input voltage and the
theoretical value (3/2LSB) when the digital output changes from 1……110 to 1……111.

(6) Differential linearity error
While the ideal width of code output is 1LSB, this indicates the difference between the actual measurement
value and the ideal value.
