X9C303

Logarithmic Digitally Controlled Potentiometer (XDCP™)

Data Sheet

January 24, 2007

FN8223.1

Terminal Voltage ±5V, 100 Taps, Log Taper

Description

The Intersil X9C303 is a digitally controlled potentiometer

(XDCP). The device consists of a resistor array, wiper

switches, a control section, and nonvolatile memory. The

wiper position is controlled by a three-wire interface.

Features

• Solid-state potentiometer

• Three-wire serial interface

• 100 wiper tap points

- Wiper position stored in nonvolatile memory and

recalled on power-up

• 99 resistive elements, log taper

- Temperature compensated

- End to end resistance, 32kΩ ±15%

- Terminal voltages, ±5V

The resistor array is composed of 99 resistive elements.

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.

• Low power CMOS

- V_CC= 5V

- Active current, 3mA max.

- Standby current, 750µA max.

The device can be used as a three-terminal potentio-meter

or as a two-terminal variable resistor in a wide variety of

applications ranging from control, to signal processing, to

• High reliability

- Endurance, 100,000 data changes per bit

- Register data retention, 100 years

parameter adjustment. Digitally-controlled potentiometers

provide three powerful application advantages; (1) the

variability and reliability of a solid-state potentiometer, (2) the

flexibility of computer-based digital controls, and (3) the use

of nonvolatile memory for potentiometer settings retention.

• Packages

- 8 Ld TSSOP

- 8 Ld SOIC

- 8 Ld PDIP
