COMMENT
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 specifi-
cation) 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
Ml Maximum.
(2) Relative linearity is a measure of the error in step size between taps = V_W(n+1)–[V_w(n) + Ml] = ±0.2 Ml.
(3) 1 Ml = Minimum Increment = R_TOT/15.
