NOTES:
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 / 1023 or (R_H – R_L) / 1023, single pot
4. V_CC, V+, V- must reach their final values within 1 msec of each other.
5. n = 0, 1, 2, …,1023; m =0, 1, 2, …, 1022.
