CAT5114VI-10-T3

Digital Potentiometers Overview

The CAT5114VI-10-T3 is a single-channel digital potentiometer manufactured by onsemi. It features a 10 kΩ resistance value with 32 discrete tap positions and linear taper characteristics. The device utilizes an increment/decrement serial interface for wiper control and includes non-volatile EEPROM memory to retain the setting during power loss. It operates on a single supply voltage ranging from 2.5 V to 6.0 V, with a typical standby current of 10 nA. The component is housed in an 8-pin SOIC package.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 10 kΩ total resistance
• Non-volatile EEPROM wiper storage retains settings after power down
• Increment/Up-Down serial control interface using CS, U/D, and INC pins
• Single supply operation from 2.5 V to 6.0 V with 10 nA ultra-low standby current

Digital Potentiometers Applications

• Automated product calibration in high-volume production lines
• Remote control adjustments for inaccessible or hazardous equipment
• Offset, gain, and zero control in signal conditioning circuits
• Tamper-proof calibration storage for security-sensitive systems
• Programmable analog functions such as contrast, brightness, and volume controls

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T3' against the official onsemi datasheet to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and lead-free/halogen-free attributes directly from the manufacturer's documentation. Check for any recent Product Change Notifications (PCN) regarding manufacturing site changes or material updates before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital replacement for mechanical potentiometers is required. Ensure the application supports the 2.5 V to 6.0 V single-supply range. Verify that the 32-tap resolution meets the system's adjustment precision needs. Confirm compatibility with the increment/decrement control logic levels and interface timing requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digitally programmable potentiometers. It serves as an electronic alternative to mechanical trim pots, offering durability and automated adjustability. The VI-10 designation indicates the 10 kΩ resistance variant in the SOIC-8 package, while the T3 suffix typically denotes reel packaging for surface-mount assembly.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include other resistance values like CAT5114VI-50 or CAT5114VI-100. Cross-manufacturer equivalents should be verified for interface compatibility and voltage ranges. Ensure any substitute maintains non-volatile memory functionality if power-down retention is critical.
