Notes:

(1)

This parameter is tested initially and after a design or process change that affects the parameter.

(2)

Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a

potentiometer.

(3)

Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potenti-

ometer. It is a measure of the error in step size.
