The Intersil ISL54209 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 2.5V to 5.0V single supply, this analog switch allows audio signal swings below ground, allowing for the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices.
The ISL54209 logic control pins are 1.8V compatible, which allows for control via a standard μcontroller.
The ISL54209 has an audio enable control pin to open all switches and put the part in a low power state. In this state, the device draws typically 1nA of current.
The ISL54209 is available in a small 10 Ld 1.8mm x 1.4mm or 2.1mmx 1.6mm ultra-thin μTQFN packages and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40°C to +85°C.
