How to give constant value to AD9106?

Hello,

What type of waveform do you want to generate out of the DAC? Please refer to FAQ numbers 4, 7, 10, 16, and 17 in AD9106 / AD9102 Low-Power DAC and Waveform Generator: FAQs.

Right now, I just wanted to send the one digital value to DAC like 2v,1.8v like this kind of can you please help me how I can

send the only single digital value. I need guidance.

Hello,

Did you get a change to look at the document linked in my previous response?

Hello , I went through the document linked that you shared to me. I want to send the 4 value to DAC, so In SRAM I set the value 4 and accordingly and write into register but no output is come on DAC cahnnel 1. I am sharing the register and its value.

here the register and its value. please guide me. 
 

Hello,

Have you compared your schematics to one in this page? https://wiki.analog.com/resources/eval/dpg/eval-ad9106

Yes, I compared the schematic its right.

When I write the registes  0x0026 to 0x3232, I am try to generate DDS waveform using START and STOP delay, after I read back registers I get the 0x3230. Why these happening three registes are read wrong. What is exact reset value 0x0026?

I am adding the excel sheet of my output please have look. I need your help.XLSX
