Description

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 V_BUS 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.
