PCM1795 Use Case of Multi Devices with the SPI Interface

Hi,

Our customers will use eight PCM1795s.
If they use the I2C interface, a maximum of four PCM1795s can be connected on the same bus at one time.
Because they would not like to increase the number of the control signal, they believe that they can use the SPI interface.
If they use the SPI interface and write same values to same registers of each device, can eight PCM1795s be connected on the same bus at one time?
In this case, they understand that they can not read back.
We believe that If it has capability for the enough drive, this use case is not problem.
Could you please advise us about it as soon as possible?

Best Regards,
Kato
