Catalyst CAT5111 Digitally Programmable Potentiometer Datasheet
The CAT5111 is a single digitally programmable potentiometer (DPP) designed as an electronic replacement for mechanical potentiometers. It features a 100-position linear taper, non-volatile memory to store the wiper position, and low power CMOS technology suitable for single supply operation between 2.5V and 6.0V.
The device is controlled via three input pins: Chip Select (CS), Up/Down (U/D), and Increment (INC). It offers various resistance values including 10kΩ, 50kΩ, and 100kΩ and is available in PDIP, SOIC, TSSOP, and MSOP packages. Applications include automated calibration, remote control adjustments, and programmable analog functions.
