onsemi Data Acquisition - Digital Potentiometers CAT5115LI00

The CAT5115LI00 is a digitally programmable potentiometer featuring a 32-position linear taper design. It operates on a single supply voltage ranging from 2.5V to 6V and utilizes low power CMOS technology, making it suitable for various applications requiring low power consumption. The device supports an up/down serial interface for wiper control, allowing for precise adjustments in automated systems. This potentiometer is available in multiple resistance values, including 10k,Ѷ, 50k,Ѷ, and 100k,Ѷ, and comes in several package types such as PDIP, SOIC, TSSOP, MSOP, and a compact 2 x 2.5mm TDFN package. The CAT5115 is ideal for applications like automated product calibration, remote control adjustments, and programmable analog functions, particularly in environments where mechanical potentiometers may be impractical. The device features a reset function that sets the wiper to the midpoint upon power-up, and it does not retain the wiper position in memory when powered down. This characteristic may be relevant for applications that do not require memory retention. Overall, the CAT5115LI00 provides a versatile solution for engineers looking to implement programmable resistance in their designs.
