Nonlinearity error : Deviation (error) in input/output curves with respect to an ideal straight line connecting
output voltage at “00” and output voltage at “FF.”
Differential linearity error : Deviation (error) in amplification with respect to theoretical increase in amplification
per 1-bit increase in digital value.

Note : The value of VAOH and VDD, and
the value of VAOL and VSS are not
necessarily equivalent.
