ABSOLUTE MAXIMUM RATINGS*
*COMMENT
Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any
other conditions outside of those listed in the operational sections
of this specification is not implied. Exposure to any absolute
maximum rating for extended periods may affect device
performance and reliability.

Note:
(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns.
Maximum DC voltage on output pins is V +0.5V, which may overshoot to V +2.0V for periods of less than 20 ns.

Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) Absolute linearity is utilitzed to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer.
(3) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a
potentiometer. It is a measure of the error in step size.
(4) LSB = RTOT / 63 or (RH - RL) / 63, single pot
