Integral non-linearity error (INL)
The integral non-linearity error is the maximum deviation between the ideal line when the measured offset and full-scale
errors are zeroed, and the actual output code.
Differential non-linearity error (DNL)
The differential non-linearity error is the difference between 1-LSB width based on the ideal D/A conversion
characteristics and the width of the actually output code.
Offset error
An offset error is the difference between a transition point of the ideal first output code and the actual first output code.
Full-scale error
A full-scale error is the difference between a transition point of the ideal last output code and the actual last output code.
