    Igor,


    1. The MMB3 motherboard is about 7.5" by 4". The EVM daughter card is about 4" by 1.75". When the daughter card is attached to the MMB3 the stack height is about 1.5".

    2. The EVM-PDK Boards for all of these ADCs are intended for lab bench evaluation and have not been specifically designed to be tested over temperature and are not rated for such operation. You'll note that the mother board has an LCD display and switches that cannot be used at higher temperatures.

    Hello Josheph,

    thank you very much.

    By the way, if you want to know the solution for a problem I posted a couple weeks ago, (see link bellow), as you suggested, after multiplexing additional waiting time of about 2ms help channels to settle and solved the problem. Therefore the channels are now independed and failure of one sensor won't influence other values.
