CAT5115  
32-Tap Digitally Programmable Potentiometer (DPP™)  
FEATURES  
DESCRIPTION  
The CAT5115 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.  
„ 32-position linear taper potentiometer  
„ Low power CMOS technology  
„ Single supply operation: 2.5V – 6V  
„ Increment up/down serial interface  
„ Resistance values: 10k, 50kand 100kΩ  
„ Available in PDIP, SOIC, TSSOP, MSOP and  
space saving 2 x 2.5mm TDFN packages  
The CAT5115 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, RW. The wiper is always set to the mid  
point, tap 15 at power up. The tap position is not  
stored in memory. Wiper-control of the CAT5115 is  
APPLICATIONS  
„ Automated product calibration  
„ Remote control adjustments  
„ Offset, gain and zero control  
„ Tamper-proof calibrations

¯
accomplished with three input control pins, CS, U/D,  
„ Contrast, brightness and volume controls  
„ Motor controls and feedback systems  
„ Programmable analog functions  
¯¯¯  
¯¯¯  
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.  
The digitally programmable potentiometer can be used  
as a three-terminal resistive divider or as a two-terminal  
variable resistor. DPPs bring variability and program-  
mability to a wide variety of applications including  
control, parameter adjustments, and signal processing.  
For Ordering Information details, see page 13.  
For a pin-compatible device that recalls a stored tap  
position on power-up refer to the CAT5114 data sheet.
