DESCRIPTION

Digitally Controlled Potentiometer

(XDCP™)

The X9Cxxx are Intersil digitally controlled (XDCP)

potentiometers. The device consists of a resistor

array, wiper switches, a control section, and nonvola-

tile memory. The wiper position is controlled by a

three-wire interface.

FEATURES

• Solid-state potentiometer

• 3-wire serial interface

• 100 wiper tap points

—Wiper position stored in nonvolatile memory

and recalled on power-up

• 99 resistive elements

—Temperature compensated

—End to end resistance, ±20%

—Terminal voltages, ±5V

• Low power CMOS

The potentiometer is implemented by a resistor array

composed of 99 resistive elements and a wiper switch-

ing network. Between each element and at either end

are tap points accessible to the wiper terminal. The

position of the wiper element is controlled by the CS,

U/D, and INC inputs. The position of the wiper can be

stored in nonvolatile memory and then be recalled

upon a subsequent power-up operation.

—V_CC= 5V

—Active current, 3mA max.

—Standby current, 750µA max.

• High reliability

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

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

variety of applications including:

—Endurance, 100,000 data changes per bit

—Register data retention, 100 years

• X9C102 = 1kΩ

• X9C103 = 10kΩ

• X9C503 = 50kΩ

– control

– parameter adjustments

– signal processing

• X9C104 = 100kΩ

• Packages

—8-lead SOIC and DIP

• Pb-free plus anneal available (RoHS compliant)
