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.brbr The ISL54210 incorporates circuitry for the detection of the USB VsubBUS/sub voltage, which is used to switch between the audio and USB signal sources.brbr 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 eliminates click and pops in the head-phones when the audio CODEC drivers are powering up/down or when a headphone is inserted or removed from the jack.brbr 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.
