DAC60508: SPI communication issue for the DAC

Hi,

From the attached scope shot, I cannot get any info.

Can you collect an oscilloscope or logic analyzer capture of the frame to ensure you are compliant with the device's timing diagram?

Also make sure you have the device with SDO functionality. Please let me know the full part number also

Regards,

AK

Hi Akhilesh,

We read the ID in the register 0X81 and the back data is all the 0XFF, and the full part# is DAC60508ZCRTE, thanks.

Hi Paul,

Thank for your kindly comment.

We test use the below program but the output is also 0xFF;

Please kindly help to provide the reference to us, thanks.

Hi Zhang,

The DAC60508ZC device does not have an SDO pin.  It does not support readback functions on the SPI bus.  You see 0xFF because the /CLR pin looks like it is being held at your supply voltage.

Thanks,

Paul

Hi Pual,

So I think your mean is we need to order the DAC60508ZRTER which support the SDO function?

or is there any solution to set the /CLR to SDO function? Thanks.

Hi Pual,

Is there are any reference program for the SPI, thanks?

Hi,

If you need SDO functionality, you need to order DAC60508ZRTER.

We dont have any reference program for this device as of now.
