'[PICLIST] [EE] audio out of max541'

can the Maxim 541 or 542 chips be used in an audio aplication? They are
16bit DAC's and they have a uniquely simple interface, making them about my
only option. Is there a way to make them not be noisy, and to play back with
all the trappings of a good audio chip? Any audio guru out there?
HELP! (thanks in advance, of course!)

I don't see why not. The basic specs look decent.

What's so hard about driving a serial-input audio DAC, like the AD1853?

Yes, a lot of complicated analog filtering of the output, which would be
simplified by the use of oversampling delta-sigma converters, and is
generally included inside a standard audio DAC.
