X9251

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

Data Sheet

April 13, 2007

FN8166.5

Quad Digitally-Controlled (XDCP™)

Potentiometer

Features

• Four potentiometers in one package

The X9251 integrates four digitally controlled potentio-

meters (XDCP) on a monolithic CMOS integrated circuit.

• 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 year 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.

• Single supply version of X9250

• Endurance: 100,000 data changes per bit per register

• 24 Ld SOIC, 24 Ld TSSOP

• Low power CMOS

• Pb-free plus anneal available (RoHS compliant)
