FN8190.4

Quad, 64 Tap, Digitally Controlled

Potentiometer (XDCP™)

Features

• Quad - 4 Separate Pots, 64 Taps/Pot

• Nonvolatile Storage of Wiper Position

• Four Nonvolatile Data Registers for Each Pot

• 16-bytes of EEPROM Memory

• SPI Serial Interface

Description

The X9401 integrates 4 digitally controlled potentiometers

(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

= 10kΩ

• Wiper Resistance = 150Ω Typical

• Standby Current < 3µA (Total Package)

• Operating Current < 700µA max.

(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.

• V

= 2.7V to 5V

• 24 Ld SOIC and 24 Ld TSSOP Package

• 100 year Data Retention

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.

• Pb-Free Available (RoHS Compliant)
