The AD9833 data sheet says "The DAC generates an output voltage of typically 0.6V p-p".
What percentage does the output voltage varies? (Output voltage variation: 0.6Vp-p +/- xx%) What is xx?
Unfortunately, the output voltage variation was not characterized.
Based on the specification, the typical Vout maximum of the DAC is 0.65V which coincides to the statement from the datasheet that you mentioned.
Does the output voltage variation depend on output frequency?
If yes, how much it varies?
I will use the AD9833 as a sinusoidal wave generator and the sinusoidal wave frequency spec is 100Hz to 1MHz.
I would like the output voltage variation as low as possible over frequencies.
The amplitude is attenuated with the output frequency, following a sinc profile, as image shows.
This is a characteristic inherent to any DAC.
Thank you for supporting this case.
I understood this is an aperture effect. Pre-equalizaion or Post-equalization filter can reduce that effect?
Im sorry but you cannot equalize as there is not direct access to the DAC.
Being said that, you could compensate the effect, an even get a pretty flat transfer function, by using the AD8337 in series.
