ISL54405IVZ-T

Analog Switches - Special Purpose Overview

The Intersil ISL54405IVZ-T is a single-supply, bidirectional, dual SPDT ultra-low distortion analog switch designed for high-fidelity audio applications. It features integrated click and pop elimination circuitry to ensure silent switching. The device operates from a single 3.3V or 5V DC supply and accommodates ground-referenced signals up to 2VRMS. Digital logic inputs are compatible with 1.8V logic levels. It provides -106dB THD+N into a 20kΩ load at 2VRMS and >124dB signal-to-noise ratio.

Analog Switches - Special Purpose Feature Summary

• Integrated click and pop elimination for silent audio switching
• Ultra-low distortion performance suitable for CD/MP3 quality audio
• Bidirectional signal passage for positive and negative ground-referenced voltages
• 1.8V logic-compatible digital control inputs

Analog Switches - Special Purpose Applications

• Computer sound cards
• Home theater audio products
• SACD/DVD audio systems
• Headsets for MP3 and cellphone switching

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer designation, as Renesas Technology Corp acquired Intersil. Confirm the specific suffix 'IVZ-T' corresponds to the TQFN package and tape-and-reel quantity in official Renesas documentation. Ensure RoHS compliance status matches current manufacturing standards.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring low distortion and silent switching in single-supply environments. It is appropriate for AC or DC coupled ground-referenced audio paths. Verify that the required signal amplitude does not exceed the 2VRMS limit when operating from the specified supply voltages.

Analog Switches - Special Purpose Part Context

This part belongs to the ISL5440x series of stereo multiplexers. It is functionally related to other variants such as the ISL54405IRUZ and ISL54406, differing primarily in packaging options like TSSOP or µTQFN. The series is targeted at consumer and professional audio switching markets.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers include ISL54405IRUZ and ISL54406IRUZ. Verify pinout compatibility and package dimensions before substitution.
