DESCRIPTION

Dual Digitally Controlled Potentiometer

(XDCP™)

The X9410 integrates two digitally controlled

potentiometers (XDCPs) on a monolithic CMOS

integrated circuit.

FEATURES

• Two potentiometers per package

• SPI serial interface

• Register oriented format

- Direct read/write/transfer wiper positions

- Store as many as four positions per

potentiometer

The digitally controlled potentiometer is implemented

using 63 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 SPI

serial bus interface. Each potentiometer has

associated with it a volatile Wiper Counter Register

(WCR) and four nonvolatile Data Registers (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 through the switches.

Power-up recalls the contents of DR0 to the WCR.

• Power supplies

- V = 2.7V to 5.5V

- V+ = 2.7V to 5.5V

- V- = -2.7V to -5.5V

• Low power CMOS

- Standby current < 1µA

- High reliability

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.

- Endurance - 100,000 data changes per bit per

- Register data retention - 100 years

• 8-bytes of nonvolatile EEPROM memory

• 10kΩ resistor arrays

• Resolution: 64 taps each pot

• 24 Ld SOIC, 24 Ld TSSOP, and 24 Ld plastic DIP

packages

• Pb-free plus anneal available (RoHS compliant)
