Digitally Controlled Potentiometer

(XDCP™)

The Intersil X9116 is a digitally controlled nonvolatile

potentiometer designed to be used in trimmer applications.

The pot consists of 15 equal resistor segments that connect

to the wiper pin through programmable CMOS switches. The

tap position is programmed through a 3-wire up/down serial

port. The last position of the wiper is stored in a nonvolatile

memory location which is recalled at the time of power up of

the device.

The wiper moves through sequential tap positions with

inputs on the serial port. A falling edge on INC (bar) causes

the tap position to increment one position up or down based

on whether the U/D (bar) pin is held high or low.

The X9116 can be used in many applications requiring a

variable resistance. In many cases it can replace a

mechanical trimmer and offers many advantages such as

temperature and time stability as well as the reliability of a

solid state solution.
