Re: dsPIC33FJ128GP802 audio DAC very noisy
If you only had read the link to the forum entry 'til the end:
there the ENOB of 9 bits is given - which may easily account for the noise.
(If you do not understand ENOB, it's time to advance your studies by looking it up on wikipedia.)
Wishful thinking / ignoring of results already available is silly- Beyond that, my footnote applies.
PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)
