CAT5114VI-10-GT3

Digital Potentiometers Overview

The CAT5114VI-10-GT3 is a single digital potentiometer IC from onsemi, designed as an electronic replacement for mechanical components. It features 32 linear taper taps and non-volatile EEPROM wiper storage to retain settings without power. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V with a standby current of 100 uA. It utilizes a serial up/down interface for control and is available in TSSOP-8 packaging. The component supports resistance values including 10 kOhms and is RoHS compliant.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM wiper storage retains calibration data after power loss
• 32-position linear taper potentiometer with up/down serial interface
• Low standby current consumption of 100 uA
• Single supply operation compatible with 2.5 V to 6.0 V systems

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Contrast, brightness, and volume controls

Digital Potentiometers Procurement Notes

Verify the specific suffix 'VI-10-GT3' against official datasheets to confirm package type (TSSOP-8) and resistance value (10 kOhms). Confirm end-of-life status and lead times directly with onsemi or authorized distributors, as availability may be restricted. Ensure environmental compliance requirements match project specifications.

Digital Potentiometers Selection Notes

Select this component when non-volatile memory is required to maintain wiper position during power cycles. Compare against volatile alternatives like the CAT5110 if power retention is unnecessary. Verify that the 32-tap resolution meets the application's precision requirements and that the serial interface protocol matches the host microcontroller capabilities.

Digital Potentiometers Part Context

This part belongs to the CAT5114 series of digitally programmable potentiometers. It shares functional similarities with other CAT51xx devices but is distinguished by its non-volatile memory feature. The 'VI' suffix typically indicates the TSSOP-8 package variant, while '10' denotes the 10 kOhm resistance value within the family.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with different resistance values or packages, such as CAT5114YI-10-GT3. For volatile-only applications, the CAT5110 series offers lower power consumption but lacks non-volatile storage. Verify pin compatibility and software register maps before substituting.
