14.The offset error (OS
e
) is the absolute difference between the straight line which fits the actual transfer curve (after removing gain error), and
a straight line which fits the ideal transfer curve. (See Figure 1.)
15.The gain error (G
) is the relative difference in percent between the straight line fitting the actual transfer curve (after removing offset error),
and the straight line which fits the ideal transfer curve. Gain error is constant at every point on the transfer curve. (See Figure 1.)
16.The absolute voltage error (A
) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve.
17.This should be considered when both analog and digital signals are simultaneously input to port 5.
