CAT5114ZI-10-G

Digital Potentiometers Overview

The CAT5114ZI-10-GT3 is a single digital potentiometer IC from onsemi, housed in an MSOP-8 package. It features a 32-tap linear taper resistor array with a nominal resistance of 10 kΩ between the high (RH) and low (RL) terminals. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V and includes non-volatile EEPROM storage for wiper position retention. Control is managed via a three-wire serial interface using CS, U/D, and INC pins. The component supports industrial operating temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 10 kΩ nominal resistance
• Non-volatile EEPROM memory retains wiper setting during power loss
• Increment/Down serial control interface requiring only three pins
• Single supply operation compatible with 2.5 V to 6.0 V logic levels

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the complete orderable part number as CAT5114ZI-10-GT3 when sourcing. Confirm that the 'Z' suffix corresponds to the MSOP-8 package and the 'I' suffix indicates the industrial temperature range. Ensure compatibility with NiPdAu lead finishes specified for this variant.

Digital Potentiometers Selection Notes

Select this model for applications requiring a compact surface-mount solution with persistent settings. The 10 kΩ value suits moderate impedance signal paths. Verify that the system can accommodate the 3-pin serial control logic. Consider the MSOP-8 footprint constraints against available PCB real estate compared to larger packages like SOIC or TSSOP.

Digital Potentiometers Part Context

This component belongs to the CAT5114 family of 32-tap digitally programmable potentiometers. The ZI-10-GT3 designation specifically identifies the MSOP-8 package, Industrial temperature grade, 10 kΩ resistance, and RoHS-compliant manufacturing. Other variants in the series offer different resistances and package types such as PDIP, SOIC, and TDFN.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5114YI-10-GT3 (TSSOP-8) and CAT5114VI-10-GT3 (SOIC-8). These share identical electrical characteristics but differ in physical package dimensions. Cross-package substitution requires verifying PCB land pattern compatibility.
