RE: Why is this a problem?

Posted by Bromo33333 on May 18, 2012 at 08:49:23:
It is easy to design a lower output voltage (we're talking about a AC signal, not a DC one) - if you needed to use a diode in the signal path, you would use AC to send the AC Zero into the linear part of the curve and then have the ausio signal ride on that. So any voltage right down to zero is easy.

However, most circuits have noise that does not change - and in a good DAC, you want to maintain -120dB from the peak - which means it has to be darn quiet and dropping the signal out by 6dB doesn't help!
