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 (R_H – R_L) / 255, single pot
13. During power up V_CC > V_H, V_L, and V_W.
14. n = 0, 1, 2, …,255; m = 0, 1, 2, …, 254.
