CAT5114YI-00-GT3

Digital Potentiometers Overview

The CAT5114YI-00-GT3 is a single digital potentiometer IC from onsemi, featuring a 100 kΩ resistance value and 32 tap positions. It utilizes a linear taper design with non-volatile EEPROM storage to retain wiper settings during power loss. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws a typical standby current of 1 µA. Control is managed via an incremental up/down serial interface using CS, U/D, and INC pins. It is housed in an 8-pin TSSOP package.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM memory retains wiper position after power down
• Increment/Decrement serial control interface (CS, U/D, INC)
• Single supply operation: 2.5 V to 6.0 V
• 100 kΩ resistance with ±20% tolerance and linear taper

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 'YI' corresponds to the TSSOP-8 package and industrial temperature range (-40°C to +85°C). Confirm the '00' designation indicates the 100 kΩ resistance value. Check for RoHS compliance and lead finish specifications (NiPdAu) as listed in the ordering information table.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer is required with a 100 kΩ range. Ensure the system supports the 3-wire incremental control interface. Verify that the 32-tap resolution meets the application's precision requirements compared to higher-resolution alternatives like the CAT5111.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. The 'Y' suffix denotes the TSSOP-8 package, while 'I' indicates the industrial temperature grade. Other variants include PDIP, SOIC, MSOP, and TDFN packages with different resistance values such as 10 kΩ or 50 kΩ.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same package and resistance value are limited due to the specific suffix combinations. Consider other CAT5114 variants with different packages if form factor changes are acceptable.
