Multiple AD7718 SPI configuration

Hi everyone,

I want to know if it's possible to connect two AD7718 as shown in the Figure 15 from AN-1248 App note. I am not sure if that ADC has a hi-Z SDO pin when inactive. The master device is a Raspbrrry Pi that controls both CS pins and reads both RDY pins.

Could be useful and would it work if we change it to daisy-chain (Figure 13)??

Best regards,

Andres
