COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” 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.
POTENTIOMETER 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 potentiom-
eter. It is a measure of the error in step size.

POWER-UP TIMING
POWER UP AND DOWN REQUIREMENT
The are no restrictions on the sequencing of the bias supplies V
CC
, V+, and V- provided that all three supplies reach
their final values within 1msec of each other. At all times, the voltages on the potentiometer pins must be less than V+
and more than V-. The recall of the wiper position from nonvolatile memory is not in effect until all supplies reach their
final value. The V
CC
ramp rate spec is always in effect.
Notes: (5) This parameter is periodically sampled and not 100% tested
(6) t
PUR
and t
PUW
are the delays required from the time the third (last) power supply (V
CC
, V+ or V-) is stable until the specific instruction can be
issued. These parameters are periodically sampled and not 100% tested.
