CAT5409  
Quad Digitally Programmable Potentiometers  
(DPP™) with 64 Taps and I²C Interface  
FEATURES  
DESCRIPTION  
„ Four linear taper digitally programmable  
The CAT5409 is four Digitally Programmable  
Potentiometers (DPP™) integrated with control logic  
and 16 bytes of NVRAM memory.  
potentiometers  
„ 64 resistor taps per potentiometer  
„ End to end resistance 2.5k, 10k, 50kor  
100kΩ  
A separate 6-bit control register (WCR) independently  
controls the wiper tap position for each DPP.  
Associated with each wiper control register are four  
6-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 I²C 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 register (WCR).  
„ I²C interface  
„ Low wiper resistance, typically 80Ω  
„ Four non-volatile wiper settings for each  
potentiometer  
„ Recall of saved wiper settings at power-up  
„ 2.5 to 6.0 volt operation  
„ Standby current less than 1µA  
„ 1,000,000 nonvolatile WRITE cycles  
„ 100 year nonvolatile memory data retention  
„ 24-lead SOIC and 24-lead TSSOP  
„ Write protection for data register  
¯¯¯  
The Write Protection (WP) pin protects against  
inadvertent programming of the data register.  
The CAT5409 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.
