Overview

The Intersil ISL54409IRTZ-T and ISL54410 are Dual SPST (Single Pole/Single Throw) switches that provide a very low distortion audio path for a stereo headphone and can be connected in a wired-OR configuration at the switch outputs with USB2.0 HS 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 ISL54409IRTZ-T and ISL54410 analog switches are negative swing capable with a single supply voltage and maintain 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 ISL54409IRTZ-T offers a Low Power Shutdown mode while the ISL54410 offers a High Off-Isolation mode. The ISL54410 contains active Audio Click and Pop Elimination circuitry for AC-coupled audio signals. The ISL54409IRTZ-T and ISL54410 are available in a 8 Ld TDFN (2mmx2mm) or a 10 Ld µTQFN (1.8mmx1.4mm) package. They operate over a temperature range of -40°C to +85°C.
