ABSOLUTE MAXIMUM RATINGS
COMMENT
Temperature under bias.................... -65°C to +135°C
Storage temperature ......................... -65°C to +150°C
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.

(5) This parameter only applies to a single potentiometer.
(6) This parameter is guaranteed by characterization.
(7) When performing multiple write operations, V
must not decrease by more than 150mV from its initial value.
