Single Digitally-Controlled (XDCP^TM) Potentiometer

FEATURES

DESCRIPTION

• 256 Resistor Taps

The X9279 integrates a single digitally controlled

• 2-Wire Serial Interface for write, read, and

transfer operations of the potentiometer

• Wiper Resistance, 100Ω typical @ 5V

• 16 Nonvolatile Data Registers for Each

potentiometer (XDCP) on

integrated circuit.

monolithic CMOS

The digital controlled potentiometer is implemented

using 255 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 2-Wire

bus interface. The potentiometer has associated with it

a volatile Wiper Counter Register (WCR) and a four

nonvolatile 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 < 5µA Max

• V : 2.7V to 5.5V Operation

• 50KΩ, 100KΩ versions of End to End Resistance

• Endurance: 100,000 Data Changes per Bit per

• 100 yr. Data Retention

• 14-Lead TSSOP, 16-Lead CSP (Chip Scale

Package)

The XDCP can be used as

a three-terminal

• Low Power CMOS

potentiometer or as a two terminal variable resistor in

a wide variety of applications including control,

parameter adjustments, and signal processing.
