CAT5269

Dual Digitally Programmable Potentiometers (DPP™)

with 256 Taps and 2-wire Interface

FEATURES

■ Two linear taper digitally programmable poten-

■ Automatic recall of saved wiper settings at

tiometers

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 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 CAT5269 is two digitally programmable

potentiometers (DPPs™) integrated with control logic

and 18 bytes of NVRAM memory. Each DPP consists of

a series of resistive elements connected between two

externallyaccessibleendpoints.Thetappointsbetween

each resistive element are connected to the wiper

outputs with CMOS switches. A separate 8-bit control

switches for 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 CAT5269 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 packages.
