Hello Kashyap

The main reason why you might not be able to see output voltage is because device is High-Z mode by default. Hence you will need to write DEVICE-MODE-CONFIG register to power it up ( page 66 of the data sheet ), once you do that you should have no problem writing to DAC_DATA register and get output going.

Hopefully that fixed the issue.

Thank you,

Hello illia

Thanks for the response.

correct me if I am wrong but, there is not mentioned about power up bit in the DEVICE-MODE-CONFIG register.
