Hello 

we need a audio switch IC which can keep the status of on without power and on/off can be controlled when powered on.

Is there any solutions?

Thanks

    Hi Jesse,

    What is the voltage level of the signal you would like to support, the signal bandwidth?

    Are you looking for a specific configuration? How do you plan to use this device in the system?  

    The audio switches we support are "Passive" switches. meaning they operate from a supply.
    We do have general-purpose audio switches like the TS3A5223 for audio signals and the TS3A225E, TS3A226AE for switching the GND/MIC connections of the audio jack via automatic detection. Please take a look at these and let us know if this is something you can use in your system?
    Thanks
