CAT5111  
100-Tap Digitally Programmable Potentiometer (DPP™)  
with Buffered Wiper  
FEATURES  
DESCRIPTION  
The CAT5111 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.  
„ 100-position linear taper potentiometer  
„ Non-volatile EEPROM wiper storage;  
buffered wiper  
„ Low power CMOS technology  
„ Single supply operation: 2.5 V - 6.0 V  
„ Increment up/down serial interface  
„ Resistance values: 10 kΩ, 50 kΩ and 100 kΩ  
The CAT5111 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, RWB. The CAT5111 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  
„ Available in PDIP, SOIC, TSSOP and MSOP  
packages  
APPLICATIONS  
„ Automated product calibration  
„ Remote control adjustments  
„ Offset, gain and zero control  
„ Tamper-proof calibrations  
setting.

is  
¯
„ Contrast, brightness and volume controls  
„ Motor controls and feedback systems  
„ Programmable analog functions  
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 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 CAT5113. The  
buffered wiper of the CAT5111 is not compatible with  
that application.
