Hi,

This is the first time that I use DDS, I am using AD9834 DDS and I got a strange output waveform see the image bellow, I was expecting a clean sine wave but we see that we have like a peak at the negative peak.

see my schematic in the second image, please would you help me to solve this problem, itried different frequencies but all are with the same shape
