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.
