*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 specification is
not implied. Exposure to absolute maximum rating condi-
tions 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) 1 Ml = Minimum Increment = R_TOT/31.
(3) Relative Linearity is a measure of the error in step size between taps = V_W(n+1) – [V_w(n) + Ml] = +0.2 Ml.
