MAX14662

Question

For MAX14662 How many devices are supported when using Daisy chain communication? When I use the Daisy chain for communication, when the number of MAX14662 is 24pcs, there is an error in the dout data, and the device cannot be closed and opened normally. What is the problem?

Hi Infi, 
 
 Please refer to the datasheet fig 15: it says 64:1 mux -- this will be 8 devices as per what is referenced in the datasheet typical. Mind you that your design is beginning to suffer from a lack of signal drive strengths available to drive the SPI lines correctly.
