Full-scale error
This is the difference between the actually measured analog input voltage and its theoretical value
when the digital output changes from 1…110 to 0…111 (full scale 3/2 LSB).
Differential linearity error
Ideally, the width to output a specific code is 1 LSB. This error indicates the difference between the
actually measured value and its theoretical value when a specific code is output.
