Low Noise/Low Power/SPI Bus

Preliminary Information

X9401

Quad, 64 Tap, Digitally Controlled Potentiometer (XDCP^™)

FEATURES

DESCRIPTION

• Quad–4 separate pots, 64 taps/pot

• Nonvolatile storage of wiper position

• Four Nonvolatile Data Registers for Each Pot

• 16-bytes of EEPROM memory

The X9401 integrates 4 digitally controlled potentiome-

ters (XDCP) on a monolithic CMOS integrated

microcircuit.

The digitally controlled potentiometer is implemented

using 64 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. Each potentiometer has associated with it a

volatile Wiper Counter Register (WCR) and 4 nonvola-

tile 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 con-

tents of DR0 to the WCR.

• SPI serial interface

• R

= 10kΩ

Total

• Wiper resistance = 150Ω typical

• Standby current < 1µA (total package)

• Operating current < 400µA max.

• V

= 2.7V to 5V

• Packages–24-lead TSSOP, SOIC, CSP (Chip

Scale Package)

• 100 year data retention

The XDCP can be used as a three-terminal potentiom-

eter or as a two-terminal variable resistor in a wide

variety of applications including control, parameter

adjustments, and signal processing.
