Note:

(1) This parameter is tested initially and after a design or process change that affects the parameter.

(2) Absolute linearity is utilitzed to determine actual wiper voltage versus expected voltage as determined by wiper position when used

as a potentiometer.

(3) 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) LSB = RTOT / 255 or (RH - RL) / 255, single pot

(5) n = 0, 1, 2, ..., 255

Note:

(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns.

Maximum DC voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns.

(2) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V.

COMMENT

Stresses above those listed under “Absolute Maximum Ratings”

may cause permanent damage to the device. These are stress

ratings only, and functional operation of the device at these or any

other conditions outside of those listed in the operational sections

of this specification is not implied. Exposure to any absolute

maximum rating for extended periods may affect device perfor-

mance and reliability.

Recommended Operating Conditions:

VCC = +2.5V to +6.0V
