3. This parameter is tested initially and after a design or process change that affects the parameter.
4. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
5. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer.
It is a measure of the error in step size.
6. LSB = RTOT / 255 or (RH RL) / 255, single pot
7. n = 0, 1, 2, ..., 255.
