  • Hi,

    Our latest overvoltage protection multiplexers are the ADG52XXF family. The ADG5209F or the ADG5249F are both differential 4:1 devices and are the highest density devices we currently have.

    These devices are available in a 4 mm x 4 mm LFCSP package offering significant size advantages over the ADG439F.

    The ADG5209F and ADG5249F are similar devices but the ADG5249F has some extra features such as

    • Digital fault flags to alert the user to the source of the fault
    • User selectable fault thresholds to set the fault level for the device.

    If you need any more information on these devices please let me know, or if you wish to share your application I can review it to see what multiplexers might suit your needs.

    Regards,

    David
