Low Power + Quad 256-tap + 2-Wire Bus + Up/Down Interface

Data Sheet

September 14, 2005

FN8167.1

Quad Digitally-Controlled (XDCP™)

Potentiometer

Features

• Quad Solid State Potentiometer

The X9252 integrates 4 digitally controlled potentiometers

(XDCP) on a monolithic CMOS integrated circuit.

• 256 Wiper Tap Points-0.4% Resolution

• 2-Wire Serial Interface for Write, Read, and Transfer

Operations of the Potentiometer

The digitally controlled potentiometers are implemented

using 255 resistive elements in a series array. Between each

pair of elements are tap points connected to wiper terminals

through switches. The position of each wiper on the array is

controlled by the user through the Up/Down (U/D) or 2-wire

bus interface. The wiper of each potentiometer has an

associated volatile Wiper Counter Register (WCR) and four

non-volatile Data Registers (DRs) that can be directly written

to and read by the user. The contents of the WCR controls

the position of the wiper on the resistor array through the

switches. At power-up, the device recalls the contents of the

default data registers DR00, DR10, DR20, DR30, to the

corresponding WCR.

• Up/Down Interface for Individual Potentiometers

• Wiper Resistance: 40Ω Typical

• Non-Volatile Storage of Wiper Positions

• Power On Recall. Loads Saved Wiper Position on Power-

Up.

• Standby Current < 20µA Max

• Maximum Wiper Current: 3mA

• V : 2.7V to 5.5V Operation

• 2.8kΩ,10kΩ, 50kΩ, 100kΩ Version of Total Pot Resistance

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

• 100 yr. Data Retention

Each DCP can be used as a three-terminal potentiometer or

as a two terminal variable resistor in a wide variety of

applications including the programming of bias voltages, the

implementation of ladder networks, and three resistor

programmable networks.

• 24 Ld TSSOP

• Pb-Free Plus Anneal Available (RoHS Compliant)
