CAT5261  
Dual Digital  
Potentiometer (POT)  
with 256 Taps  
and SPI Interface  
Description  
http://onsemi.com  
The CAT5261 is two digital POTs integrated with control logic and  
8 bytes of NVRAM memory. Each digital POT consists of a series of  
resistive elements connected between two externally accessible end  
points. The tap points between 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  
digital POT. 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 SPI serial bus. On power-up, the  
contents of the first data register (DR0) for each of the potentiometers  
is automatically loaded into its respective wiper control register.  
The CAT5261 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. It is available in the  
40C to 85C industrial operating temperature range and offered in a  
24-lead SOIC and TSSOP package.
