Part Number: DAC80508
I would like to know whether there's any operation I need to do before I sending read / write SPI commands to operate DAC80508?
I tried to read DAC80508 register DEVICE ID register by issuing 0x82, 0x00, 0x00, and trigger another data cycle after 1ms for retrieving read result, as figure below.
However, I got nothing while I issuing second data cycle, what might go wrong?
The operating conditions is as below:
VDD = 5.0 , VIO = 3.0V, Temperator = 25°C
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to user5941200:
After posting this question, I bought a DAC80508EVM too and got it these days, and it works correctly with GUI.
And I finally found that I might get DAC80508C rather than DAC80508 since I found the SDO pin behaves like the CLR pin.
For another problem on failing to writing DAC is due to the SDI pin is interfered by other pins.
So I have few questions about DAC80508C:
1. If there's no SDO pin, there's no read operation so we are not able to get the registers' state, right?
2. And further, how does error checking work on DAC80508C?
Thank you so much for your help!
Ok, thanks a lot for your help!
