CAT5112  
32-Tap Digitally Programmable Potentiometer (DPP™)  
with Buffered Wiper  
FEATURES  
DESCRIPTION  
The CAT5112 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.  
„ 32-position linear taper potentiometer  
„ Non-volatile EEPROM wiper storage;  
buffered wiper  
„ Low power CMOS technology  
„ Single supply operation: 2.5V - 6.0V  
„ Increment up/down serial interface  
„ Resistance values: 10kΩ, 50kΩ and 100kΩ  
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 memory, is not lost when the  
device is powered down and is automatically recalled  
when power is returned. The wiper can be adjusted to  
test new system values without effecting the stored  
setting. Wiper-control of the CAT5112 is accompli-  
„ Available in PDIP, SOIC, TSSOP and MSOP  
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  
¯¯  
¯
¯¯¯  
shed 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 digitally programmable potentiometer can be  
used as a buffered voltage divider. For applications  
where the potentiometer is used as a 2-terminal  
variable resistor, please refer to the CAT5114. The  
buffered wiper of the CAT5112 is not compatible with  
that application.  
For Ordering Information details, see page 10.
