Nonlinearity error:
Deviation (error) in input/output
curves with respect to an ideal
straight line connecting output
voltage at “06” 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 GND are not necessarily equivalent.
