CAT5114ZI-50-T3

Digital Potentiometers Overview

The CAT5114ZI-50-T3 is a single digitally programmable potentiometer from onsemi, housed in an MSOP-8 package. It features a 50 kΩ resistance value with linear taper and 32 tap positions. The device utilizes a nonvolatile EEPROM to store wiper settings, ensuring data retention during power loss. Control is managed via a serial interface using CS, U/D, and INC pins. It operates on a single supply voltage ranging from 2.5 V to 6.0 V.

Digital Potentiometers Feature Summary

• Nonvolatile EEPROM storage retains wiper position after power down
• 32-position linear taper potentiometer with 50 kΩ nominal resistance
• Increment/Down serial control interface (CS, U/D, INC)
• Single supply operation from 2.5 V to 6.0 V

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions

Digital Potentiometers Procurement Notes

Verify the specific ordering suffixes for package type and lead finish when sourcing. The 'Z' suffix indicates the MSOP-8 package, while 'GT3' denotes tape and reel packaging with NiPdAu lead finish. Confirm availability as component status may change over time.

Digital Potentiometers Selection Notes

Select this part for applications requiring electronic replacement of mechanical potentiometers where space is limited due to the compact MSOP-8 footprint. Ensure the system voltage falls within the 2.5 V to 6.0 V range and that the 32-tap resolution meets the required adjustment precision.

Digital Potentiometers Part Context

This component belongs to the CAT5114 series of 32-tap digitally programmable potentiometers. The ZI-50 variant specifically designates the MSOP-8 package, industrial temperature range (-40°C to +85°C), and 50 kΩ resistance value. Other variants exist with different resistances and packages.

Digital Potentiometers Replacement Considerations

Compatible replacements include other CAT5114 series parts with matching resistance and package, such as CAT5114VI-50-GT3 (SOIC-8) or CAT5114LI-50-G. Verify pin compatibility and electrical specifications before substitution.
