X9316

Digitally-Controlled (XDCP™) Potentiometer

FEATURES

DESCRIPTION

• Solid-State Potentiometer

• Three-Wire Serial Interface

• Low Noise

The Xicor X9316 is a digitally-controlled (XDCP)

potentiometer. 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.

• 32 Wiper Tap Points

—Wiper position stored in nonvolatile memory

and recalled on power-up

• 31 Resistive Elements

—Temperature compensated

—End to end resistance range ± 20%

—Terminal voltages, -5V to +5V

• Low Power CMOS

The potentiometer is implemented by a resistor array

composed of 31 resistive elements and a wiper

switching 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 = 5V

—Active current, 3mA max.

—Standby current, 1µA max.

• High Reliability

—Endurance, 100,000 data changes per bit

—Register data retention, 100 years

The device can be used as a three-terminal

potentiometer or as a two-terminal variable resistor in

a wide variety of applications including:

• R

Values = 1KΩ, and 10KΩ

TOTAL

• Packages

—14-lead SOIC and DIP

– control

– parameter adjustments

– signal processing
