X9268

Dual Digitally-Controlled (XDCP^TM) Potentiometers

FEATURES

DESCRIPTION

• Dual–Two separate potentiometers

• 256 resistor taps/pot–0.4% resolution

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

transfer operations of the potentiometer

• Wiper Resistance, 100Ω typical @ V+ = 5V, V- = -5V

• 16 Nonvolatile Data Registers for Each

Potentiometer

• Nonvolatile Storage of Multiple Wiper Positions

• Power On Recall. Loads Saved Wiper Position on

Power Up.

The X9268 integrates

potentiometer (XDCP) on

integrated circuit.

digitally controlled

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. Each 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.ꢀV to 5.5V Operation

Ω

• 50K , 100K versions of End to End Pot

Resistance

• Endurance: 100,000 Data Changes per Bit per

• 100 yr. Data Retention

• 24-Lead SOIC, 24-Lead XBGA

• 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.
