The Intersil ISL54211 dual SPDT (Single Pole/Double Throw) switches combine 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 5.0V 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 ISL54211 logic control pins are 1.8V compatible with a supply voltage of 2.7V to 3.6V, which allows for control via a standard μcontroller.
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 10Ld 1.8mm x 1.4mm ultra-thin μTQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40 to +85°C
