FN8178.2

Single Digitally Controlled Potentiometer

(XDCP™)

Features

• Solid State Potentiometer

• 32 Taps

The Intersil X9314 is a solid state nonvolatile potentiometer and

is ideal for digitally controlled resistance trimming.

• 10kΩ End to End Resistance

• Three-Wire Up/Down Serial Interface

• Wiper Resistance, 40Ω Typical

The X9314 is a resistor array composed of 31 resistive

elements. Between each element and at either end are tap

points accessible to the wiper element. 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.

• Nonvolatile Storage and Recall on Power-up of Wiper

Position Standby Current < 500µA Max (Total Package)

• V

= 3V to 5.5V Operation

• 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.

• Offered in 8 Ld MSOP, SOIC and PDIP Packages

• Pb-Free Plus Anneal Available (RoHS Compliant)
