CAT5259

Quad Digitally Programmable Potentiometers (DPP™)

with 256 Taps and 2-wire Interface

FEATURES

■ Four linear taper digitally programmable

■ Automatic recall of saved wiper settings at

potentiometers

power up

■ 256 resistor taps per potentiometer

■ End to end resistance 50kΩ or 100kΩ

■ 2.5 to 6.0 volt operation

■ Standby current less than 1 µA

■ 1,000,000 nonvolatile WRITE cycles

■ 100 year nonvolatile memory data retention

■ 24-lead SOIC and 24-lead TSSOP packages

■ Industrial temperature range

■ Potentiometer control and memory access via

2-wire interface (I²C like)

■ Low wiper resistance, typically 100Ω

■ Nonvolatile memory storage for up to four

wiper settings for each potentiometer

DESCRIPTION

The CAT5259 is four digitally programmable

potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

a series of resistive elements connected between two

externallyaccessibleendpoints.Thetappointsbetween

eachresistiveelementareconnectedtothewiperoutputs

with CMOS switches. A separate 8-bit control register

(WCR)independentlycontrolsthewipertapswitchesfor

each DPP. Associated with each wiper control register

are four 8-bit non-volatile memory data registers (DR)

used for storing up to four wiper settings. Writing to the

wiper control register or any of the non-volatile data

registers is via a 2-wire serial bus. On power-up, the

contents of the first data register (DR0) for each of the

four potentiometers is automatically loaded into its

respective wiper control registers.

The CAT5259 can be used as a potentiometer or as a

two terminal, variable resistor. It is intended for circuit

level or system level adjustments in a wide variety of

applications.Itisavailableinthe0˚Cto70˚Ccommercial

and -40˚C to 85˚C industrial operating temperature

ranges and offered in a 24-lead SOIC and TSSOP

package.
