What sort of filters should I use to use the AD5930 as a general waveform generator up to 20MHz?
The AD5930 only needs external filters if you want to clean your signals of harmonics.
This is up to you but in any case a requirement for the AD5930 functionality.
If helps, we typically use a elliptic filter mainly bc the attenuation is quite fast for a relative low order filter.
Thank you musach, it was very helpful. I will apply an elliptical filter, but using the AD9834 insetad of the AD5930 in order to reach the mentioned frecuencies.
