Description
The ISL54409 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 ISL54409 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 ISL54409 offers a low power shutdown mode and is available in an 8 Ld TDFN (2mm x 2mm) or a 10 Ld µTQFN (1.8mm x 1.4mm) package. The device operates over a temperature range of -40 °C to +85 °C.
