FN8191.4

Quad Digitally Controlled (XDCP™)

Potentiometers

Features

• Four Potentiometers in One Package

• 64 Resistor Taps per Potentiometer

• 2-wire Serial Interface

Description

The X9408 integrates four digitally controlled potentiometers

(XDCP) on a monolithic CMOS integrated circuit.

• Wiper Resistance, 40Ω Typical at 5V

• Four Nonvolatile Data Registers for Each Pot

• Nonvolatile Storage of Wiper Position

• Standby Current < 1µA max (Total Package)

The digital 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 2-wire bus interface. Each

potentiometer has associated with it a volatile Wiper Counter

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. Power-up recalls the contents of

the default data register (DR0) to the WCR.

• V

= 2.7V to 5.5V Operation

V+ = 2.7V to 5.5V

V- = -2.7V to -5.5V

• 10kΩ, 2.5kΩ End to End Resistances

• High reliability

• Endurance–100,000 Data Changes Per Bit Per Register

• Register Data Retention–100 years

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.

• 24 Ld SOIC, 24 Ld TSSOP, 24 Ld PDIP Packages

• Pb-Free (RoHS Compliant)
