CAT5114VI-50-GT3

Digital Potentiometers Overview

The CAT5114VI-50-GT3 is a single-channel digital potentiometer from onsemi, housed in an SOIC-8 surface-mount package. It provides 32 linear tap positions with a nominal resistance of 50 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. Wiper position control utilizes a three-pin serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC). A key feature is the non-volatile EEPROM memory that retains the wiper setting during power-down events.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM storage for wiper position retention across power cycles
• 32-position linear taper potentiometer with 50 kΩ nominal resistance
• Increment/Decrement serial interface controlled by CS, U/D, and INC pins
• Single supply operation within 2.5 V to 6.0 V range

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 suffix 'GT3' corresponds to tape and reel shipping quantities when sourcing. Confirm the 'V' suffix indicates the SOIC-8 package variant. Ensure the order includes the '-G' designation for RoHS compliance if required by manufacturing standards. Cross-reference the full part number against current distributor catalogs to confirm availability status.

Digital Potentiometers Selection Notes

Select this component when a 50 kΩ digital potentiometer with non-volatile memory is required. The SOIC-8 package suits applications needing surface-mount assembly. Verify that the 32-tap resolution meets system precision requirements. Ensure the control logic can drive the CS, U/D, and INC inputs within the specified voltage levels.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. The VI suffix denotes the industrial temperature range (-40°C to +85°C) and SOIC-8 package. Other variants in the series offer different resistance values (10 kΩ, 100 kΩ) and package options such as PDIP, TSSOP, MSOP, and TDFN.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with matching resistance and package, such as CAT5114VI-10-GT3 or CAT5114VI-00-GT3. Alternative packages like TSSOP (Y suffix) or MSOP (Z suffix) require schematic review for pin compatibility.
