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.

POWER-UP AND DOWN REQUIREMENTS
The are no restrictions on the power-up or power-down conditions of V_CC and the voltages applied to the poten-
tiometer pins provided that V_CC is always more positive than or equal to V_H, V_L, and V_W, i.e., V_CC ≥ V_H, V_L, V_W.
The V_CC power-up spec is always in effect.
Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a
potentiometer.
(2) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiom-
eter. It is a measure of the error in step size.
(3) MI = RTOT/63 or (V_H - V_L)/63, single pot
