CAT5114ZI-10-GT3

Digital Potentiometers Overview

The CAT5114ZI-10-GT3 is a single digital potentiometer IC from onsemi, featuring 32 linear taper positions. It operates within a supply voltage range of 2.5 V to 6.0 V and utilizes a non-volatile EEPROM to retain wiper settings during power loss. The device employs an increment/up-down serial interface controlled by CS, U/D, and INC pins. Packaged in an MSOP-8 (Z suffix) with NiPdAu lead finish, it serves as an electronic replacement for mechanical potentiometers in automated calibration and remote adjustment applications.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with non-volatile EEPROM storage
• Single supply operation: 2.5 V to 6.0 V
• Increment/Up-Down serial interface (CS, U/D, INC)
• MSOP-8 package with NiPdAu lead finish

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the Z suffix indicates the MSOP-8 package and the '10' code specifies the 10 kΩ resistance value. Confirm the GT3 designation aligns with the required shipping format, which is listed as 96 units per rail for this specific part number in the ordering information table.

Digital Potentiometers Selection Notes

Select this component when a compact MSOP-8 footprint is required alongside non-volatile memory retention. Ensure the system logic levels are compatible with the CMOS input specifications defined for the 2.5 V to 6.0 V operating range. Verify that the 32-tap resolution meets the application's precision requirements compared to higher-resolution alternatives.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. The 'ZI' suffix combination denotes the MSOP-8 package and Industrial temperature range (-40°C to +85°C). The '10' indicates the 10 kΩ nominal resistance, while 'GT3' specifies the tape and reel or rail shipping configuration.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with different packages such as CAT5114YI-10-GT3 (TSSOP-8) or CAT5114VI-10-GT3 (SOIC-8), provided the pinout compatibility is verified. Cross-family substitutes like the CAT5111 series offer different tap counts and should be evaluated based on resolution needs.
