Voltage on CS, INC, U/D and VCC
with respect to VSS ................................. -1V to +7V
âV = |VH - VL| ........................................................ 15V

COMMENT
Stresses above those listed under âAbsolute Maximum
Ratingsâ may cause permanent damage to the device.
This is a stress rating only; 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
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) Relative linearity is a measure of the error in step size between taps = RW(n+1 - [Rw(n) + Ml] = ±0.2 Ml.
(3) 1 Ml = Minimum Increment = RTOT/99.
