X9111

Single Supply/Low Power/1024-Tap/SPI Bus

Data Sheet

March 25, 2005

FN8159.1

Single Digitally-Controlled (XDCP™)

Potentiometer

Features

• 1024 Resistor Taps – 10-Bit Resolution

The X9111 integrates a single digitally controlled

potentiometer (XDCP) on a monolithic CMOS integrated

circuit.

• SPI Serial Interface for Write, Read, And Transfer

Operations Of The Potentiometer

• Wiper Resistance, 40Ω Typical @ 5V

• Four Non-Volatile Data Registers

The digital controlled potentiometer is implemented using

1023 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 SPI bus interface. The

potentiometer has associated with it a volatile Wiper Counter

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 though the switches. Powerup recalls the contents of

the default data register (DR0) to the WCR.

• Non-Volatile Storage of Multiple Wiper Positions

• Power On Recall. Loads Saved Wiper Position on Power

Up.

• Standby Current < 3µA Max

• V : 2.7V to 5.5V Operation

• 100kΩ End to End Resistance

• 100 yr. Data Retention

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.

• Endurance: 100, 000 Data Changes Per Bit Per Register

• 14-Lead TSSOP

• Low Power CMOS

• Single Supply version of the X9110
