Preliminary Information

Single Digitally-Controlled (XDCP^™) Potentiometer

FEATURES

DESCRIPTION

• 1024 Resistor Taps – 10-Bit Resolution

• SPI Serial Interface for write, read, and transfer

operations of the potentiometer

The X9111 integrates a single digitally controlled

potentiometer (XDCP) on

integrated circuit.

monolithic CMOS

• Wiper Resistance, 40Ω Typical @ 5V

• Four Non-Volatile Data Registers

• Non-Volatile Storage of Multiple Wiper Positions

• Power On Recall. Loads SavedWiper Position on

Power Up.

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 Register (WCR) and

four non-volatile Data Registers 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 though the switches. Powerup recalls the

contents of the default data register (DR0) to the WCR.

• Standby Current < 3µA Max

• V : 2.7V to 5.5V Operation

• 100KΩ End to End Resistance

• 100 yr. Data Retention

• Endurance: 100, 000 Data Changes Per Bit Per

• 14-Lead TSSOP, 15-Lead CSP (Chip Scale

Packaging)

• Low Power CMOS

• Single Supply version of the X9110

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.
