We are using AD7276 in our project for clock synchronization. I have a doubt on whether AD7276 has to be configured at Power ON or with no configuration required, it starts the conversion process & sends the data as the CS goes low.
Let me check on this. I'll get back to you soon.
I moved this question about the AD7276 in the Precision ADCs Community. Someone here should be able to assist you.
The AD7276 does not have special registers that need to be configured. After power-up, a falling edge on /CS will initiate conversions.
