Method and system for digital to analog conversion

A digital audio system having an analog to digital converter for providing a digital signal and a digital signal processor responsive to the digital signal, comprising:

• a first plurality of digital to analog converters connected in parallel for providing a first plurality of output signals, each of said first plurality of digital to analog converters responsive to the digital signal;
• a first summer connected to said first plurality of digital to analog converters, said first summer providing a first electrical sum of said first plurality of output signals;
• an inverter responsive to the digital signal for providing a negative of said digital signal;
• a second plurality of digital to analog converters connected in parallel for providing a second plurality of output signals, each of said second plurality of digital to analog converters responsive to said negative of the digital signal;
• a second summer connected to said second plurality of digital to analog converters, said second summer providing a second electrical sum of said second plurality of output signals;
• a first analog reconstruction filter responsive to said first electrical sum;
• and,
• a second analog reconstruction filter responsive to said second electrical sum.

A method for converting an analog signal to a digital signal, the method comprising the steps of:

• applying the digital signal to a first plurality of digital to analog converters;
• summing electrically an output of each of said of said first plurality of digital to analog converters for providing a first electrical sum;
• inverting the digital signal to provide a negative of the digital signal;
• applying the negative of the digital signal to a second plurality of digital to analog converters;
• and,
• summing electrically an output of each of said second plurality of digital to analog converters for providing a second electrical sum.
