Dear sir:

   I am encountering a problem of AD7175 continuous conversion issue. The waveform 1 as below shows there's no issue on RDY_/DOUT data rate when directly pull CS low without 0x44 command. Data rate is ~250ksps. But if add 0x44 command after falling edge of RDY_/DOUT (waveform 2). The data rate is changed to 1/68.93us = 14.507ksps.

 

 

Thank you!
