NOTES:
10. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
11. 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.
12. MI = RTOT / 255 or (RH - RL)/255, single pot
13. During power-up VCC > VH, VL, and VW.
