OUTPUT FILTERS

Post by Mcfly » Tue Nov 10, 2015 8:53 am

Hi! I'm running this simple program:

rdax adcr,1
wrax wrax dacr,0

Circuit is: Input Buffer=>FV1=>Output buffer

Im feeding the input with a sinewave 1vpp, and at the output of the FV1 the signal is slightly weaker (10% or 15% less tan the input). Is this normal?

I've noticed that the datasheet suggest for the fv1output a 3.3uf, 10k, 1k and 2.2nf. If i measure with the scope between 3.3.uf and 1K signal is not attenuated. Is there a solution for this?
