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 con-

ditions 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

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

(4) Individual array resolutions.
