NOTES:

Integral Non-Linearity : The difference between the digital data converted DC analog values and a

reference straight line drawn through the first and the last output values

Differential Non-Linearity : The difference between the ideal and real increment value of DC analog voltage

when the digital data increase 1 bit.
