Hello, I'm having trouble figuring out how to regulate output voltage from AD9833. I was thinking of applying the signal to the input of multiplying DAC (AD5432) in order to achieve digital regulation. However i do have some doubts with this design. First, I only have single 5v supply in my device, and while there is a single supply multiplying DAC in voltage mode circuit mentioned in datasheet, I do not really know if the DAC will work in its full range.
And secondly, is the input signal frequency limited to 1,25MHz because of DAC's 2,5MSPS sample rate, or mentioned 10MHz bandwith?
Appreciate all answers
