CAT5261

Dual Digitally Programmable Potentiometer (DPP™) with

256 Taps and SPI Interface

FEATURES

■ Automatic recall of saved wiper settings at

■ Two linear-taper digitally programmable

power up

potentiometers

■ 2.5 to 6.0 volt operation

■ 256 resistor taps per potentiometer

■ End to end resistance 50kΩ or 100kΩ

■ Standby current less than 1µA

■ 100 year nonvolatile memory data retention

■ 24-lead SOIC and 24-lead TSSOP

■ Industrial temperature range

■ Potentiometer control and memory access via

SPI interface

■ Low wiper resistance, typically 100Ω

■ Nonvolatile memory storage for up to four wiper

settings for each potentiometer

DESCRIPTION

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

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

potentiometersisautomaticallyloadedintoitsrespective

wiper control register.

The CAT5261 is two Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 8 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

The CAT5261 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. Itisavailableinthe-40°Cto85°Cindustrial

operating temperature range and offered in a 24-lead

SOIC and TSSOP package.
