Hi,
We are working on energy meter IC ADE9078. Our micro controller is used to communicate with three energy meter IC through three SPI Isolator ADUM3150.
While reading value of VLEVEL status from three energy meter, it showing always zero. It's not reading proper also.
Note: we have put tri-state buffer on energy meter side and SPI Isolator.
In ADUM3150 datasheet , it mention don't need of tri-state buffer while using this isolator. But if we removed two SPI isolator, one energy meter is working fine.
Please give suggest us to get out of this problem.
Regards,
