CAT5114ZI-00-G

Digital Potentiometers Overview

The CAT5114ZI-00-G is a single digital potentiometer IC from onsemi, featuring a 100 kΩ resistance value with linear taper and 32 tap positions. It utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. The device incorporates nonvolatile EEPROM memory to retain wiper settings during power loss. Operating on a single supply voltage ranging from 2.5 V to 6.0 V, it draws low standby current. The component is housed in an MSOP-8 package (Z suffix) with NiPdAu lead finish, suitable for industrial temperature ranges of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM storage retains wiper position across power cycles
• Increment/Up-Down serial control interface requiring only three pins
• Single supply operation compatible with 2.5 V to 6.0 V logic levels
• MSOP-8 surface-mount package with industrial temperature rating

Digital Potentiometers Applications

• Automated product calibration systems
• Remote control adjustments for inaccessible equipment
• Offset, gain, and zero control in instrumentation
• Programmable analog functions such as volume or brightness controls

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'ZI' corresponds to the MSOP-8 package and '00' indicates the 100 kΩ resistance value. Confirm RoHS compliance status and check for any end-of-life notifications or alternative package recommendations from onsemi before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this part when a 100 kΩ digital potentiometer with nonvolatile memory is required in a compact MSOP-8 footprint. Ensure the system interface supports the Up/Down control logic. Verify that the 100 kΩ resistance tolerance of ±20% meets the application's linearity requirements.

Digital Potentiometers Part Context

This component belongs to the CAT5114 family of 32-tap digital potentiometers. The 'ZI' suffix designates the MSOP-8 package variant, while '00' specifies the 100 kΩ nominal resistance. Other variants include 10 kΩ and 50 kΩ options available in PDIP, SOIC, TSSOP, and TDFN packages.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include CAT5114VI-00-G (SOIC-8) and CAT5114LI-00-G (PDIP-8). Cross-package substitutions require verifying pin compatibility and thermal performance differences between MSOP-8 and alternative footprints.
