ISL54210

The ISL54210 dual Single Pole/Double Throw (SPDT) 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 V_BUS voltage, which is used to switch between the audio and USB signal sources. It has an enable pin (CTRL) to open all switches and activate the audio click/pop (C/P) circuitry. The high off-isolation and special C/P circuitry of the audio switches eliminate clicks and pops in the headphones when the audio CODEC drivers are powering up/down or when a headphone is inserted or removed from the jack. It's available in a tiny 10 Ld 1.8mm x 1.4mm ultra-thin µTQFN package and a 10 Ld 3mm x 3mm TDFN package. It operates over a temperature range of -40 °C to +85 °C.
