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. n = 0, 1, 2, …,1023; m =0, 1, 2, …, 1022.
5. ESD Rating on RH, RL, RW pins is 1.5kV (HBM, 1.0µA leakage maximum), ESD rating on all other pins is 2.0kV.
