AD7134 SPI connection

Question

I would like to connect multiple AD7134 devices together and control these via the SPI interface. Does the AD7134 support daisy chaining the SPI interfaces?

Hi, 
 The SPI interface is used for configuring the ADCs and the parallel interface for data output, AD7134 supports daisy chain for its data output. Please see Daisy-Chaining section (Page 61) of the https://www.analog.com/media/en/technical-documentation/data-sheets/ad7134.pdf for more details. 
 I am not sure if daisy chaining the SPI interface is possible, but I think sharing SPI interface is possible but you just need to use separate /CS line for each devices and configure each devices at a time. 
 I have contacted the product owner to support you better. 
 Thanks,
