CAT5419  
DualDigitallyProgrammablePotentiometers(DPP™)with  
64 Taps and 2-wire Interface  
TM  
FEATURES  
■ Two linear-taper digital potentiometers  
■ 64 resistor taps per potentiometer  
■ Recall of wiper settings at power up  
■ 2.5 to 6.0 volt operation  
■ End-to-end resistance 2.5kΩ, 10kΩ, 50kΩ or 100kΩ  
■ Standby current less than 1µA  
■ 1,000,000 nonvolatile WRITE cycles  
■ Potentiometer control and memory access via  
2-wire interface (I2C like)  
■ 100 year nonvolatile memory data retention  
■ 24-lead SOIC, 24-lead TSSOP and BGA  
■ Write protection for data register  
■ Low wiper resistance, typically 80Ω  
■ Four non-volatile wiper settings for each  
potentiometer  
DESCRIPTION  
firstdataregister(DR0)foreachofthetwopotentiometers  
is automatically loaded into its respective wiper control  
registers (WCR).  
The CAT5419 is two Digitally Programmable  
Potentiometers (DPP™) integrated with control logic  
and 16 bytes of NVRAM memory.  
The Write Protection (WP) pin protects against  
inadvertent programming of the data register.  
A separate 6-bit control register (WCR) independently  
controlsthewipertappositionforeachDPP. Associated  
with each wiper control register are four 6-bit non-  
volatile memory data registers (DR) used for storing up  
tofourwipersettings.Writingtothewipercontrolregister  
or any of the non-volatile data registers is via a 2-wire  
serial bus (I2C-like). On power-up, the contents of the  
The CAT5419 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.
