Single Supply/Low Power/256-Tap/SPI Bus Single, Digitally Controlled (XDCP™)

Potentiometer

The X9271 integrates a single, digitally controlled

potentiometer (XDCP™) on a monolithic CMOS integrated

circuit.

Features

• 256 Resistor Taps

• SPI Serial Interface for Write, Read, and Transfer

Operations of Potentiometer

The digitally controlled potentiometer is implemented by

using 255 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 SPI bus interface. The

potentiometer has associated with it a volatile Wiper Counter

be directly written to and read by the user. The contents of

the WCR control 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.

• Wiper Resistance, 100Ω typical at V

• 16 Nonvolatile Data Registers

= 5V

• Nonvolatile Storage of Multiple Wiper Positions

• Power-on Recall; Loads Saved Wiper Position on

Power-up

• Standby Current <3µA Max

• V

= 2.7V to 5.5V Operation

• 50kΩ End-to-End Resistance

• 100-yr 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.

• Endurance: 100,000 Data Changes per Bit per Register

• 14-Lead TSSOP

• Low-power CMOS

• Pb-Free Plus Anneal Available (RoHS Compliant)
