Single Digitally Controlled (XDCP) Potentiometer

FEATURES

DESCRIPTION

• Solid-State Potentiometer

• SPI serial interface

• Register oriented format

—Direct read/write/transfer wiper positions

—Store as many as four positions per

potentiometer

The X9420 integrates a single digitally controlled

potentiometers (XDCP) on a monolithic CMOS

integrated microcircuit.

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 bus

interface. The potentiometer has associated with it a

• 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

—Endurance–100,000 data changes per bit per

—Register data retention–100 years

• 8-bytes of nonvolatile EEPROM memory

• 10KΩ or 2.5KΩ resistor arrays

• Resolution: 64 taps each pot

• 14-lead TSSOP, 16-lead SOIC, and 16-pin plastic

DIP packages

volatile Wiper Counter Register (WCR) and

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.

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.
