CAT5114VI-50-G

Digital Potentiometers Overview

The CAT5114VI-50-G is a single digital potentiometer IC from onsemi, featuring 32 linear taper tap positions and a nominal resistance of 50 kΩ. It utilizes an increment/up-down serial interface controlled by CS, U/D, and INC pins. The device incorporates nonvolatile EEPROM memory to retain the wiper setting during power loss, automatically recalling it upon power restoration. Operating on a single supply voltage ranging from 2.5 V to 6.0 V, it draws a typical standby current of 1 µA. The component is housed in an SOIC-8 package with NiPdAu lead finish.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 50 kΩ nominal resistance
• Nonvolatile EEPROM storage retains wiper position across power cycles
• Increment/Up-Down serial control interface (CS, U/D, INC)
• Single supply operation: 2.5 V to 6.0 V with low standby current

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 'V' confirms the SOIC-8 package and 'I' indicates the industrial temperature range (-40°C to +85°C). Confirm the '-GT3' shipping designation matches the required tape and reel quantity of 100 units per rail as specified in the ordering information table.

Digital Potentiometers Selection Notes

Select this part for applications requiring electronic replacement of mechanical pots where power-down retention is critical. Ensure the system logic levels are compatible with the CMOS input thresholds defined for the 2.5 V to 6.0 V supply range. Verify that the 32-tap resolution meets the precision requirements of the target application.

Digital Potentiometers Part Context

This component belongs to the CAT5114 family of 32-tap digital potentiometers. The 'VI' designation specifies the Industrial temperature grade and SOIC-8 package variant. Other variants in the series include different resistance values (10 kΩ, 100 kΩ) and packages such as PDIP, MSOP, TSSOP, and TDFN.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5114LI-50-G (PDIP), CAT5114ZI-50-G (MSOP), and CAT5114YI-50-G (TSSOP). Ensure the substitute maintains the SOIC-8 footprint if board space constraints apply.
