NOTES:
5. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
6. 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.
7. MI = RTOT/1023 or (RH – RL)/1023, single pot
8. VCC, V+, V- must reach their final values within 1ms of each other.
9. n = 0, 1, 2, …,1023; m = 0, 1, 2, …, 1022.
