    Hi Mark 

    The Schematic for this device looks correct and should be fine for this application 

    I do see there are currently no DC blocking caps in the design but this should be fine as long as the CMV connected to the mux from all other devices is within the range 0 to 1.8V

    There are many applications where DC blocking caps are not needed so this should be fine.

    However if you have any questions in the future from customers about this concept this FAQ should be helpful on whether they need DC blocking caps or not

    Regards,

    Kameron
