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.
(4) LSB = RTOT / 255 or (RH - RL) / 255, single pot
(5) n = 0, 1, 2, ..., 255.
