  • In 3 AD7980 systems, when AD7980A completes sending data, the SDOs of AD7980B and AD7980C will output data at the same time, which may cause conflicts. But in 2 AD7980 systems, when AD7980A completes sending data, only AD7980B is waiting. There are no problem with the 2 AD7980 systems. I don't know what I can do?
