CAT5116  
Log-Taper, 100-Tap Digitally Programmable Potentiometer (DPP™)  
FEATURES  
DESCRIPTION  
„ 100-position, log-taper potentiometer  
„ Non-volatile EEPROM wiper storage  
„ 10nA ultra-low standby current  
„ Single-supply operation: 2.5V – 5.5V  
„ Increment Up/Down serial interface  
„ Resistance value: 32kΩ  
The CAT5116 is a log-taper single digitally program-  
mable potentiometer (DPP™) designed as a electro-  
nic replacement for mechanical potentiometers.  
Ideal for automated adjustments on high volume  
production lines, DPP ICs are well suited for applica-  
tions where equipment requiring periodic adjustment  
is either difficult to access or located in a hazardous or  
remote environment.  
„ Available in 8-pin MSOP, TSSOP, SOIC and DIP  
packages  
The CAT5116 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.  
APPLICATIONS  
„ Automated product calibration  
„ Remote control adjustments  
„ Offset, gain and zero control  
„ Audio volume control  
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 effecting the stored setting.  
„ Sensor adjustment  
„ Motor controls and feedback systems  
„ Programmable analog functions  
Wiper-control of the CAT5116 is accomplished with  
¯¯  
¯
¯¯¯  
¯¯¯  
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.  
For Ordering Information details, see page 11.  
The digitally programmable potentiometer can be used  
as a three-terminal resistive divider or as a two-terminal  
variable resistor.
