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

Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when
used as a potentiometer.
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.
MI = RTOT/63 or (VHâVL)/63, single pot
