CAT5114YI-00-G

Digital Potentiometers Overview

The CAT5114YI-00-G is a single digital potentiometer IC from onsemi, featuring 32 linear taper taps and non-volatile EEPROM wiper storage. It operates within a supply voltage range of 2.5 V to 6.0 V with a standby current of typically 1 µA. The device utilizes an Up/Down serial interface controlled by CS, U/D, and INC pins. It provides a resistance value of 100 kΩ with ±20% tolerance and a temperature coefficient of 300 ppm/°C. Packaged in a TSSOP-8 (Y suffix) format, it retains settings across power cycles.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM memory retains wiper position during power loss
• Up/Down serial interface for simple control logic
• Single supply operation from 2.5 V to 6.0 V
• Linear taper with 32 tap positions

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'Y' corresponds to the TSSOP-8 package and '00' indicates the 100 kΩ resistance value. Confirm RoHS compliance status as per the manufacturer's latest documentation. Check for any End-of-Life notifications or alternative package availability if long-term supply assurance is required.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with a 100 kΩ resistance value is needed. Ensure the application supports the Up/Down control interface rather than a standard SPI/I2C protocol. Verify that the operating voltage range of 2.5 V to 6.0 V aligns with the system power rails.

Digital Potentiometers Part Context

This part belongs to the CAT5114 series of 32-tap digital potentiometers. The 'Y' suffix denotes the TSSOP-8 surface-mount package, while '00' specifies the 100 kΩ nominal resistance. Other variants exist with different resistance values (10 kΩ, 50 kΩ) and packages such as PDIP or SOIC.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with different resistance values or packages, such as CAT5114VI-00-G (SOIC-8) or CAT5114LI-00-G (PDIP-8), provided pin compatibility is maintained.
