The Intersil ISL54215 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 ISL54215 logic control pins are 1.8V compatible, which
allows for control via a standard microcontroller.
The ISL54215 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 ISL54215 is available in a small 10 Ld 2.1mmx1.6mm
ultra-thin μTQFN package. It operates over a temperature
range of -40°C to +85°C.
