You are right data words also for the other channels are seen with oscilloscope. The issue has to be in the receiver side in spite of the fact that the number of bits to be received has been set to 64.

Sorry, could you give me the standard pricing for 5x pieces and for 100x pieces?
View ArticleForum Post: RE: DAC8831: noisy output
Hi Chen, Good to see adding an RC filter helped mitigate some of the noise. A capacitor between RFB and VOUT is correct for question 1. Combining all three methods would help. The DAC8831 is an old...
