In my application, five or more sensors are required to sample at the same instance (audio frequency single-ended). Reference Figure 58 in the datasheet. If I use five ADS8860, the DOUT frame size of 5 x 16 bits = 80 bits at an SCLK of 10MHz should be sufficient. However, MCU that I'm familiar with can only support SPI frame size of 8-16 bits. Without a custom FPGA SPI implementation, it seems daisy-chain five or more ADS8860 would not be feasible. Do you have any suggestions? or are you aware of any MCUs out there that can support this implementation?
