COMMENT

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

speciﬁcation) is not implied. Exposure to absolute

maximum rating conditions for extended periods may

affect device reliability.

ANALOG CHARACTERISTICS (Over recommended industrial 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.

(3) MI = RTOT / 255 or (RH – RL) / 255, single pot

(4) During power up VCC > VH, VL, and VW.

(5) n = 0, 1, 2, …,255; m =0, 1, 2, …., 254.
