Part Number: DAC80508

Hai,

        In my design,   I have used QSPI to communicate with DAC80508MRTET. Currently,  MISO is not getting properly. Is there any particular steps to be followed to configure communication with DAC via QSPI

    Hi Arjun,

    I think you can start by checking a few things:

    1. Confirm the device you are using is the 80508M, not the MC or ZC.  On the "C" variants, the SDO pin is replaced with a CLR pin.  You can look at the device markings to confirm.

    2. Have you confirmed with an oscilloscope that the SDO output from the DAC is idle? Are you successfully writing to the device?

    thanks,
    Paul
