So I need to access six ADC devices using a SPI communication protocol. Apart from the SPI pins, I have a START, RESET, DRDY, and CS pin for EACH ADC for which I need to use 3x8:1 demultiplexers and 1x1:8 multiplexer.
I was thinking of maybe associating the SAME address for all the demultiplexers and multiplexer to link to the SAME ADC and was wondering if the same address lines could be used for multiple multiplexers.
So, if I use D4,D5,D6 as the address lines and connect them to the S0,S1,S2 pins of ALL demultiplexers and multiplexer, would setting the output of these pins to one value and enabling all the demultiplexers and multiplexers allow me to communicate with one of the ADCs?
Or do I have to use individual address lines for each multiplexer?
I hope my question is clear and would be really grateful if anyone could help.
