13.1 Definitions
It is defined as the deviation of the transfer function from a best fit straight line (linear
regression computation). The INL of the code i is obtained from the equation:
where
S = slope of the ideal straight line = code width; i = code value.
It is the deviation in code width from the value of 1 LSB.
