CAT5114  
32-Tap Digitally Programmable Potentiometer (DPP™)  
FEATURES  
DESCRIPTION  
„ 32-position linear taper potentiometer  
„ Non-volatile EEPROM wiper storage  
„ Low standby current  
The CAT5114 is a single digitally programmable  
potentiometer (DPP™) designed as a electronic  
replacement for mechanical potentiometers and trim  
pots. Ideal for automated adjustments on high volume  
production lines, they are also well suited for  
applications where equipment requiring periodic  
adjustment is either difficult to access or located in a  
hazardous or remote environment.  
„ Single supply operation: 2.5V – 6V  
„ Increment up/down serial interface  
„ Resistance values: 10kΩ, 50kΩ and 100kΩ  
„ Available in PDIP, SOIC, TSSOP, MSOP and  
The CAT5114 contains a 32-tap series resistor array  
connected between two terminals RH and RL. An up/  
down counter and decoder that are controlled by three  
input pins, determines which tap is connected to the  
wiper, RW. The wiper setting, stored in nonvolatile  
memory, is not lost when the device is powered down  
and is automatically reinstated when power is  
returned. The wiper can be adjusted to test new  
system values without affecting the stored setting.  
Wiper-control of the CAT5114 is accomplished with  
space saving 2 x 2.5mm TDFN packages  
APPLICATIONS  
„ Automated product calibration  
„ Remote control adjustments  
„ Offset, gain and zero control  
„ Tamper-proof calibrations  
„ Contrast, brightness and volume controls  
„ Motor controls and feedback systems  
„ Programmable analog functions

three input control pins, CS, U/D, and INC. The INC  
input increments the wiper in the direction which is  
¯
¯¯  
determined by the logic state of the U/D input. The CS  
input is used to select the device and also store the  
wiper position prior to power down.  
The digitally programmable potentiometer can be  
used as a three-terminal resistive divider or as a two-  
terminal variable resistor. DPPs bring variability and  
programmability to a wide variety of applications  
including control, parameter adjustments, and signal  
processing.
