*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

= (Vw(n)(actual) – Vw(n)(expected)) = ±1 Ml Maximum.

(2) 1 Ml = Minimum Increment = RTOT/31.

(3) Relative Linearity is a measure of the error in step size between taps = VW(n+1) – [Vw(n) + Ml] = +0.2 Ml.
