CAT5114VI-00-GT3

Digital Potentiometers Overview

The CAT5114VI-00-GT3 is a single digital potentiometer IC from onsemi, featuring a 100 kΩ resistance value and 32 tap positions. It utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. The device incorporates non-volatile EEPROM memory to retain the wiper setting during power-down, automatically restoring it upon power-up. Operating on a single supply voltage ranging from 2.5 V to 6.0 V, it offers low standby current and linear taper characteristics. Housed in an SOIC-8 package with a 'V' suffix, this industrial-grade component serves as an electronic replacement for mechanical potentiometers.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 100 kΩ nominal resistance
• Non-volatile EEPROM storage retains wiper position after power loss
• Increment/Up-Down serial control interface (CS, U/D, INC)
• Single supply operation: 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 suffix 'GT3' corresponds to tape and reel shipping quantities of 100 units per rail for the SOIC-8 package. Confirm that the 'I' temperature range indicates industrial specifications (-40°C to +85°C). Ensure compatibility with NiPdAu lead finish requirements for the assembly process.

Digital Potentiometers Selection Notes

Select the CAT5114VI-00-GT3 when a 100 kΩ resistance value is required alongside non-volatile memory retention. The SOIC-8 package is suitable for surface mount applications requiring standard spacing. Compare against volatile counterparts if power-on reset states are acceptable, or choose different resistance values (10 kΩ or 50 kΩ) based on circuit impedance needs.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digitally programmable potentiometers. The 'VI' designation identifies the SOIC-8 package variant with industrial temperature rating. Other variants include PDIP, TSSOP, MSOP, and TDFN packages, offering flexibility for different PCB layout constraints while maintaining identical electrical functionality.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5114VI-10-GT3 (10 kΩ) and CAT5114VI-50-GT3 (50 kΩ). For different packaging, equivalent parts are available in TSSOP-8 (Y suffix), MSOP-8 (Z suffix), and TDFN-8 (VP2 suffix). Verify that substitute components maintain the same non-volatile memory and interface logic levels.
