Dear Sir/Madam,

 

I am just studying your DDS AD9833.

So I have a question for you.

 

How can I think about the secular distortion of output frequency? after 10 years, 20 years, etc.....

On your datasheet and in your homepage I could not find the rating.

It means you cannot guarantee directly, I understand.

What is your change factor?

I also saw the following your thinking.

But I could not catch the answer well.....

Maybe another products also same, I think.

Please let me know

 

Thanks Kaos
