CAUTION: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only; 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 = (V_W(n)(actual) - V_{W(n)(expected)}) = ±1 MI maximum.
2. Relative linearity is a measure of the error in step size between taps = R_W(n+1) - (R_W(n) + MI) = ±0.2 MI.
3. 1 MI = minimum increment = R_TOT / 31.
