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 reli-

ability.

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 potenti-

ometer. It is a measure of the error in step size.

(4) Individual array resolutions
