The Intersil ISL54210 dual SPDT (Single Pole/Double Throw) switch combines low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.7V to 3.6V single supply, these analog switches allow audio signal swings below-ground, allowing the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices.
The ISL54210 incorporates circuitry for the detection of the USB VBUS voltage, which is used to switch between the audio and USB signal sources.
The part has an audio enable control pin (CTRL) to open all in-line switches and activate the audio click and pop circuitry. The high off-isolation and special click/pop circuitry of the audio switches eliminates click and pops in the head-phones when the audio CODEC drivers are powering up or down or when a headphone is inserted or removed from the headphone jack.
It's available in a tiny 10 Ld 1.8mmx1.4mm ultra-thin μTQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40°C to +85°C.
