ANALOG CHARACTERISTICS (Over recommended industrial (2.7V) operation 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 / 1023 or (RH – RL) / 1023, single pot

(4) n = 0, 1, 2, …,1023; m =0, 1, 2, …, 1022.

(5) ESD Rating on RH, RL, RW pins is 1.5KV (HBM, 1.0µA leakage maximum), ESD rating on all other pins is 2.0kV.

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.
