Hello.
I Measured the output of a AVCC trident installed on a Buffalo DAC.

They have a small oscillation that I hope can be improved .

Any ideas to solve?

Thank avr300.

I had already read but the ripple was not equal in form, frequency or amplitude.
Is much smaller 0.2 mV pp. and 100 hz.
I don´t know if it is the same solution, but I try.

No, the solution suggested will not improve 100Hz.

Can you post a picture of your DAC. I'll like to see the layout. To me it sounds like EMI or ground loop.

Or could it be the measurement method (/gear) ?

Yes that looks like a very clear ground loop. :)
