Overview
The UM4684EEUE is a low-voltage dual single-pole double-throw (SPDT) analog switch manufactured by Union Semiconductor. It features an extremely low on-resistance of 0.5 ohms, enabling high-fidelity signal transmission in precision applications. The device is designed for operation with single supply voltages, making it suitable for modern low-power systems. It integrates two independent SPDT switches within a compact package, providing efficient signal routing capabilities. The component supports bidirectional analog signals and maintains consistent performance across the operating voltage range.
Feature Summary
- Dual SPDT configuration for independent signal path management
- Ultra-low on-resistance of 0.5 ohms for minimal signal attenuation
- Low-voltage operation capability for compatibility with modern power domains
Applications
- Signal routing in portable electronic devices
- Audio and video signal switching circuits
- Data acquisition systems requiring precise analog switching
Procurement Notes
Verify the specific suffix EEUE corresponds to the TSSOP-16 package variant when sourcing. Confirm that the 0.5-ohm on-resistance specification aligns with your application's impedance requirements. Ensure the supplier provides documentation confirming compliance with the manufacturer's electrical characteristics for this specific package type.
Selection Notes
Select this component when dual independent analog switching is required with minimal insertion loss. The low on-resistance makes it preferable over standard CMOS switches for high-frequency or high-precision applications. Consider the package size constraints as it utilizes a small outline footprint suitable for dense PCB layouts.
Part Context
This part belongs to the UM4684 series of low-voltage analog switches from Union Semiconductor. The series includes variants such as UM4684H and UM4684EEUE, all sharing the core 0.5-ohm on-resistance characteristic. The family is designed to replace higher-cost solutions in consumer electronics and industrial control applications where signal integrity is critical.
Replacement Considerations
Potential substitutes include the LMS4684 from Texas Instruments and the AS1746 from ams AG, which offer similar 0.5-ohm on-resistance specifications. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit.
