AD5752 SPI Issue

Hello,

 

I have connected an AD5752 to an SPI bus in which there are a number of devices, for example an EEPROM. When the DAC is not connected, everything works fine, but when I connect it, I just get 0s every time I read data from the EEPROM. I am keeping the AD5752 SYNC signal high, but its SDO line is always low, so I guess that is the reason why I am just reading 0s. I am not using a daisy chain by the way.

 

Is the AD5752 is sending data (zeros from its internal registers) because of the clock pulses even though SYNC is kept high?

 

Thanks in advance!
