CAT5113  
100-Tap Digitally Programmable Potentiometer (DPP™)  
FEATURES  
DESCRIPTION  
„ 100-position linear taper potentiometer  
„ Non-volatile EEPROM wiper storage  
„ 10nA ultra-low standby current  
The CAT5113 is a single digitally programmable  
potentiometer (DPP™) designed as a electronic  
replacement for mechanical potentiometers. 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 – 6.0V  
„ Increment up/down serial interface  
„ Resistance values: 1k, 10k, 50kand 100kΩ  
„ Available in PDIP, SOIC, TSSOP and MSOP  
The CAT5113 contains a 100-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 CAT5113 is accomplished with  
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.
