CAT5269  
Dual Digitally Programmable Potentiometers (DPP™)  
with 256 Taps and 2-wire Interface  
TM  
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  
register (WCR) independently controls the wiper tap  
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.
