DESCRIPTION  
system values without effecting the stored  
setting. Wiper-control of the CAT5112 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 CAT5112 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 buffered voltage divider. For applications  
wherethepotentiometerisusedasa2-terminalvariable  
resistor, please refer to the CAT5114. The buffered  
wiper of the CAT5112 is not compatible with that appli-  
cation. DPPs bring variability and programmability to a  
broad range of applications and are used primarily to  
control, regulate or adjust a characteristic or parameter  
of an analog circuit.  
The CAT5112 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, RWB. The CAT5112 wiper is buffered by an op  
amp that operates rail to rail. The wiper setting, stored in  
non-volatile NVRAM memory, is not lost when the de-  
viceispowereddownandisautomaticallyrecalledwhen
