The spi interface of the AD7768-1 is connected to the spi of the CPU
Do they need to be isolated directly? What makes sense?

Hi syncadc007 ,
Can you clarify further what you mean by spi of CPU? There are reference designs and evaluation board in the product page below that could provide some insights.

Hi,Janine
the spi of cpu...for example, zynq or MCU,which has the spi interface. Usually, we use the spi master of mcu to control the spi slave of ad7768-1. I don't confirm if it needs isolator between the spi master(MCU) and the spi slave(AD7768-1).
Hope your reply

Hi syncadc007 ,
Isolation between the MCU and ADC will depend on the system environment and application used (like existence of high voltage transients and interference). Can you share what your application is?
Thanks,
Janine
