FN8173.1

DESCRIPTION

Dual Digitally-Controlled (XDCP™)

Potentiometers

The X9269 integrates

potentiometer (XDCP) on

integrated circuit.

digitally controlled

monolithic CMOS

FEATURES

• Dual–Two separate potentiometers

• 256 resistor taps/pot–0.4% resolution

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

transfer operations of the potentiometer single

supply device

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.

• Wiper Resistance, 100Ω typical V

= 5V

• 4 Nonvolatile Data Registers for Each

Potentiometer

• Nonvolatile Storage of Multiple Wiper Positions

• Power-on Recall. Loads Saved Wiper Position on

Power-up.

• Standby Current < 5µA Max

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

Resistance

• 100 yr. Data Retention

The XDCP can be used as a three-terminal

• Endurance: 100,000 Data Changes per Bit per

• 24-Lead SOIC, 24-Lead TSSOP

• Low Power CMOS

potentiometer or as a two terminal variable resistor in

a wide variety of applications including control,

parameter adjustments, and signal processing.

• Power Supply V

= 2.7V to 5.5V
