CAT5114YI-10-G

Digital Potentiometers Overview

The CAT5114YI-10-G is a single digital potentiometer IC from onsemi, featuring 32 linear taper tap positions. It operates within a supply voltage range of 2.5 V to 6.0 V and draws a typical standby current of 1 µA. The device utilizes a nonvolatile EEPROM to retain wiper settings during power loss. Control is managed via a three-wire serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC) pins. The component is housed in an 8-pin TSSOP package with NiPdAu lead finish.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with nonvolatile EEPROM storage
• Single supply operation ranging from 2.5 V to 6.0 V
• Increment Up/Down serial control interface requiring only three pins
• Low standby current consumption of typically 1 µA

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions such as volume or brightness controls

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'YI' corresponds to the TSSOP-8 package and industrial temperature grade (-40°C to +85°C). Confirm that the '-G' suffix indicates RoHS compliance and halogen-free construction. Ensure the resistance value '10' matches the required 10 kΩ specification for the application circuit.

Digital Potentiometers Selection Notes

Select this component when a digitally programmable resistor with memory retention is required. The 32-tap resolution provides approximately 3.2% step accuracy. Verify that the system logic levels are compatible with the CMOS input thresholds defined for the CS, INC, and U/D pins. Consider the TSSOP-8 package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. The 'Y' suffix designates the TSSOP-8 package, 'I' indicates the industrial temperature range, and '10' specifies the 10 kΩ resistance value. Other variants in the series include different resistance values (50 kΩ, 100 kΩ) and package types such as PDIP, SOIC, MSOP, and TDFN.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same package and electrical specifications include CAT5114VI-10-G (SOIC-8) and CAT5114ZI-10-G (MSOP-8) if package adaptation is permitted. For different resistance values, CAT5114YI-50-G (50 kΩ) and CAT5114YI-00-G (100 kΩ) share identical control interfaces and pinouts.
