DP7112

32-Tap Digital Potentiometer (DP)

with Buffered Wiper

Description

The DP7112 is

single digital potentiometer (DP)

designed as an electronic replacement for mechanical

potentiometers. 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.

SOICï8

The DP7112 contains a ꢀꢁïWDS series resistor array connected

MSOPï8

between two terminals R and R . An up/down counter and decoder

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

connected to the wiper, R . The DP7112 wiper is buffered by an op

amp that operates rail to rail. The wiper setting, stored in nonïvolatile

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

automatically recalled when power is returned. The wiper can be

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

Wiperïcontrol of the DP7112 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 buffered voltage

divider. For applications where the potentiometer is used as a

2ïterminal variable resistor, please refer to the DP7114. The

buffered wiper of the DP7112 is not compatible with that

application.
