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.
