ISL22346WM

Quad Digitally Controlled Potentiometers (XDCP™)

The ISL22346WMVEP integrates four digitally controlled

potentiometers (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

The digitally controlled potentiometers are implemented with

a combination of resistor elements and CMOS switches. The

position of the wipers are controlled by the user through the

volatile Wiper Register (WR) and a non-volatile Initial Value

Register (IVR) that can be directly written to and read by the

user. The contents of the WR controls the position of the

wiper. At power-up, the device recalls the contents of the two

DCP’s IVR to the corresponding WRs.

The DCPs can be used as a three-terminal potentiometers

or as a two-terminal variable resistors in a wide variety of

applications including control, parameter adjustments and

signal processing.

Device Information

The specifications for an Enhanced Product (EP) device are

defined in a Vendor Item Drawing (VID), which is controlled

by the Defense Logistics Agency (DLA). “Hot-links” to the

applicable VID and other supporting application information

are provided on our website.
