X9241A

Low Power/2-Wire Serial Bus

Data Sheet

September 15, 2005

FN8164.1

Quad Digitally Controlled Potentiometer

(XDCP™)

Features

• Four potentiometers in one package

The X9241A integrates four digitally controlled

potentiometers (XDCP) on a monolithic CMOS integrated

microcircuit.

• 2-wire serial interface

• Register oriented format

- Direct read/write/transfer of wiper positions

- Store as many as four positions per

potentiometer

The digitally controlled potentiometer is implemented using

63 resistive elements in a series array. Between each

element are tap points connected to the wiper terminal

through switches. The position of the wiper on the array is

controlled by the user through the 2-wire bus interface. Each

potentiometer has associated with it a volatile Wiper Counter

• Terminal Voltages: +5V, -3.0V

• Cascade resistor arrays

• Low power CMOS

(DR0:DR3) that can be directly written to and read by the

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

wiper on the resistor array through the switches. Power up

recalls the contents of DR0 to the WCR.

• High Reliability

- Endurance–100,000 data changes per bit per register

- Register data retention–100 years

• 16-bytes of nonvolatile memory

The XDCP can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including control, parameter adjustments, and

signal processing.

• 3 resistor array values

- 2kΩ to 50kΩ mask programmable

- Cascadable for values of 500Ω to 200kΩ

• Resolution: 64 taps each pot

• 20 Ld plastic DIP, 20 Ld TSSOP and 20 Ld SOIC

packages

• Pb-free plus anneal available (RoHS compliant)
