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
specification) is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect device reliability.

ANALOG CHARACTERISTICS
(Over recommended operating conditions unless otherwise stated.)
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 poten-
tiometer. It is a measure of the error in step size.
(3) MI = RTOT/63 or (V
