Hi Katlynne, Thank you for your response. I have changed the SPI settings to use the second clock edge, and I am currently getting 1.2V on the DAC output. I do have a question regarding the external 2.5V reference voltage. To enable this, I understand that I need to send 0x0001 to the gain register. However, when I do this, the DAC output shows 0V. On the other hand, when I send 0x0100 , which I believe sets the DAC to use the internal reference voltage, I get 1.2V on the DAC output while sending 0xFFFF as the DAC data. Could you please check if I am making any mistakes in this setup? Thank you in advance for your help!
