X9259

Single Supply/Low Power/256-Tap/2-Wire bus

Data Sheet

September 16, 2005

FN8169.2

Quad Digitally-Controlled (XDCP™)

Potentiometers

Features

• Four Separate Potentiometers in One Package

The X9259 integrates four digitally controlled potentio-

meters (XDCP) on a monolithic CMOS integrated circuit.

• 256 Resistor Taps–0.4% Resolution

• 2-Wire 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 2-wire 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

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

• 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.

• Single Supply Version of X9258

• 24 Ld SOIC, 24 Ld TSSOP

• Low Power CMOS

• Pb-Free Plus Anneal Available (RoHS Compliant)
