CAT5114VI-00-T3

Digital Potentiometers Overview

The CAT5114VI-00-T3 is a single digitally programmable potentiometer (DPP) from onsemi, designed as an electronic replacement for mechanical components. It features a 32-tap linear taper resistor array with a nominal resistance of 100 kΩ between terminals RH and RL. The device utilizes non-volatile EEPROM to store wiper positions, ensuring settings are retained during power loss. Control is managed via a three-pin Increment/Up-Down serial interface (CS, U/D, INC). It operates on a single supply voltage ranging from 2.5 V to 6.0 V and is housed in an SOIC-8 package.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 100 kΩ nominal resistance
• Non-volatile EEPROM wiper storage retains position after power down
• Increment Up/Down serial control interface using CS, U/D, and INC 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 calibrations
• Programmable analog functions

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T3' indicates tape and reel packaging containing 3,000 units per reel. Confirm the 'V' suffix corresponds to the SOIC-8 package and '00' denotes the 100 kΩ resistance value. Ensure the component meets industrial temperature range requirements (-40°C to +85°C) if applicable to the design environment.

Digital Potentiometers Selection Notes

Select this part when a non-volatile digital solution is required to replace mechanical trimmers in space-constrained designs. The 100 kΩ resistance value suits applications requiring higher impedance nodes. The SOIC-8 package is suitable for surface mount assembly. Verify that the 32-step resolution meets the precision requirements of the target application.

Digital Potentiometers Part Context

This component belongs to the CAT5114 family of 32-tap Digitally Programmable Potentiometers. The VI-00-T3 designation specifies the SOIC-8 package variant with 100 kΩ resistance and tape-and-reel packaging. Other variants in the series include different resistance values (10 kΩ, 50 kΩ) and packages such as PDIP, TSSOP, MSOP, and TDFN.

Digital Potentiometers Replacement Considerations

Direct pin-compatible substitutes within the same family include CAT5114VI-10-T3 (10 kΩ) and CAT5114VI-50-T3 (50 kΩ). For different package requirements, consider CAT5114ZI-00-GT3 (MSOP-8) or CAT5114YI-00-GT3 (TSSOP-8), maintaining the 100 kΩ resistance and tape-and-reel format.
