*COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and the functional operation
of the device at these or any other conditions above
those listed in the operational sections of this specifica-
tion 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
= (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum.
(2) 1 Ml = Minimum Increment = RTOT/99.
(3) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = +0.2 Ml.
