CAUTION: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; the functional
operation of the device (at these or any other conditions above those listed in the operational sections of this specification) is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

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