DP7114

32-Tap Digital Potentiometer (DP)

Description

The

DP7114

is

a

single

digital

potentiometer

(DP)

designed

as

an

electronic

replacement

for

mechanical

potentiometers and trim pots. Ideal for automated adjustments on high

volume production lines, they are also well suited for applications

where equipment requiring periodic adjustment is either difficult to

access or located in a hazardous or remote environment.

The DP7114 contains a

series resistor array connected

that are controlled by three input pins, determines which tap is

memory, is not lost when the device is powered down and is

automatically reinstated when power is returned. The wiper can be

adjusted to test new system values without affecting the stored setting.

Wiper control of the DP7114 is accomplished with three input

control pins, CS, U/D, and INC. The INC input increments the wiper

in the direction which is determined by the logic state of the U/D input.

The CS input is used to select the device and also store the wiper

position prior to power down.

The digital potentiometer can be used as a

terminal

resistive

divider

or

as

a

variable

resistor.

DPs bring variability and programmability to a wide variety of

applications including control, parameter adjustments, and signal

processing.
