DESCRIPTION  
new system values without effecting the stored  
setting. Wiper-control of the CAT5113 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.  
The CAT5113 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.  
The digitally programmable potentiometer can be  
used as a three-terminal resistive divider or as a  
two-terminalvariableresistor.DPPsbringvariabilityand  
programmability to a wide variety of applications  
including control, parameter adjustments, and  
signal processing.  
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
