DESCRIPTION  
test new output values without effecting the stored  
settings and stored settings can be read back without  
disturbing the DPP’s output.  
The CAT525 is a quad 8-bit digitally programmable  
potentiometer (DPP™) configured for programmable  
voltage and DAC-like applications. Intended for final  
calibrationofproductssuchascamcorders,faxmachines  
and cellular telephones on automated high volume  
production lines and systems capable of self calibration,  
it is also well suited for applications were equipment  
requiring periodic adjustment is either difficult to access  
or located in a hazardous environment.  
Control of the CAT525 is accomplished with a simple 3-  
wire, Microwire-like serial interface. A Chip Select pin  
allows several CAT525's to share a common serial  
interfaceandcommunicationsbacktothehostcontroller  
is via a single serial data line thanks to the CAT525’s Tri-  
Stated Data Output pin. A RDY/BSY output working in  
concert with an internal low voltage detector signals

Write cycle.  
The CAT525 offers four independently programmable  
DPPs each having its own reference inputs and each  
capable of rail to rail output swing. The wipers are  
buffered by rail to rail op amps. Wiper settings, stored in  
non-volatile NVRAM memory, are not lost when the  
deviceispowereddownandareautomaticallyreinstated  
when power is returned. Each wiper can be dithered to  
The CAT525 is available in the 0°C to 70°C commercial  
and -40°C to 85°C industrial operating temperature  
ranges and offered in 20-pin plastic DIP and surface  
mount packages.
