1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
2. 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.
3. MI = RTOT/255 or (RH - RL)/255, single pot
4. During power up VCC > VH, VL, and VW.
5. n = 0, 1, 2, …,255; m = 0, 1, 2, …, 254.
