X9251

Single Supply/Low Power/256-Tap/SPI Bus

Data Sheet

September 14, 2005

FN8166.2

DESCRIPTION

Quad Digitally-Controlled (XDCP™)

Potentiometer

The X9251 integrates four digitally controlled potentio-

meters (XDCP) on a monolithic CMOS integrated

circuit.

FEATURES

• Four potentiometers in one package

• 256 resistor taps–0.4% resolution

• SPI Serial Interface for write, read, and transfer

operations of the potentiometer

The digitally controlled potentiometers are imple-

mented with a combination of resistor elements and

CMOS switches. The position of the wipers are

controlled by the user through the SPI bus interface.

Each 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 content of the WCR controls the

position of the wiper. At power-up, the device recalls

the content of the default Data Registers of each DCP

(DR00, DR10, DR20, and DR30) to the corresponding

WCR.

• Wiper resistance: 100Ω typical @ V

= 5V

• 4 Non-volatile data registers for each

potentiometer

• Non-volatile storage of multiple wiper positions

• Standby current < 5µA max

• V : 2.7V to 5.5V Operation

• 50kΩ, 100kΩ versions of total resistance

• 100 yr. data retention

• Single supply version of X9250

• Endurance: 100,000 data changes per bit per

• 24 Ld SOIC, 24 Ld TSSOP

• Low power CMOS

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.

• Pb-free plus anneal available (RoHS compliant)
