Multiple AD7746 on the same bus

Hello everyone,

   I wonder if there is a way (by Hw or SW) to connect several AD7746 CDC on the same bus to read multiple channels with high precision (24 bits). AD7147 has 13 channels but is 16 bits, and I need to read more sensors.

  Since the start byte address is 0x90 to write, and 0x91 to read (constants), is there any procedure to reprogram or reassign the address from the MCU?.

 

Thanks in advance for your help.

 

Best Regards,

 

Frankot.
