Low Noise/Low Power/2-Wire Bus/256 Taps Quad Digital Controlled

Potentiometers (XDCP™)

The X9258 integrates 4 digitally controlled potentiometers

(XDCP™) on a monolithic CMOS integrated circuit.

Features

• Four potentiometers in one package

The digitally 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. Each

potentiometer has associated with it a volatile Wiper Counter

(DR0:DR3) 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. Power-up

recalls the contents of DR0 to the WCR.

• 256 resistor taps/potentiometer................. 0.4% resolution

• 2-wire serial interface

• Wiper resistance, 40Ωtypical @ V+ = 5V, V- = -5V

• Four nonvolatile data registers for each potentiometer

• Nonvolatile storage of wiper position

• Standby current <5µA max (total package)

• Power supplies

- V

= 2.7V to 5.5V

- V+ = 2.7V to 5.5V

- V- = -2.7V to -5.5V

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.

• 100kΩ, 50kΩtotal potentiometer resistance

• High reliability

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

- Register data retention . . . . . . . . . . . . . . . . . . 100 years

• 24 Ld SOIC, 24 Ld TSSOP

• Dual supply version of X9259

• Pb-free (RoHS compliant)
