Hi all,
I recently bought a TPA buffaloIII and would like to try the v-out mode without external I/V stage.
After some internet search I figured it would be wise to implement a low pass R/C filter on the output.
I found a TI application note for their Delta-Sigma DAC range and they show a "classic" R/C low pass with a 10uF in the signal path ahead of it.
Now the question, what exactly is the purpose of that (rather big) 10uF cap ahead of the filter ?
Any help is highly appreciated!
Cheers,
Max
