The ISL54410 is a dual single-pole/single-throw (SPST) switch that provides a very low distortion audio path for a stereo headphone and can be connected in a wired-OR configuration at the switch outputs with USB 2.0 High-Speed signals for audio/USB signal multiplexing to a common connector. The audio switch path can be disabled to provide high signal isolation, preventing crosstalk between the audio codec and USB data signals. The ISL54410 analog switch is negative swing capable with a single supply voltage and maintains excellent THD performance within a signal range of -1V to +1V. The switch terminals have low pin capacitance (4pF typical), minimizing impact to USB 2.0 High-Speed signals. The device offers a high off-Isolation mode and contains active audio click and pop elimination circuitry for AC-coupled audio signals. The ISL54410 is available in an 8 Ld TDFN (2mm x 2mm) or a 10 Ld µTQFN (1.8mm x 1.4mm) package and operates over a temperature range of -40 °C to +85 °C.
