I am trying to model a 16bit DAC in MATLAB with its nonlinearities
and practical impariments. Does anyone have any idea how to do this ?

Matlab or Simulink? Simulink has a quantization block, Matlab probably
makes you roll your own -- you can just use floor(x) if you don't mind
quantizing in steps of 1.0.
Integral and differential nonlinearities will be tougher, because a data
sheet will only spec the worst-case, and it won't be very forthcoming
about the nature of the nonlinearities that you can expect. If you
really need accuracy there you have some studying to do.
