Do we have a quad SPST Analog Switch with dual power supply (similar to Vishay's DG9424)?

    Sonia,

    I typed the DG9424 in the TI.com competitive part selection tool and found the following results which got me in the ballpark.

    I found this switch in the TS12A family but it is only single channel and would need to have 4x TS12A4516 if you are switching 4 signals. 

    What type of signals are you tying to isolate?  Do you know their bandwidth, voltage range, etc?

    Why do you need to have a dual supply switch? 

    Will a single ended supply device work? 

    Could you use a different reference for a single ended supply device to create a dual supply device?

    Thank you,

    Adam
