Design and Build Digital Audio Circuit

Job Description


We are putting together a digital audio circuit.

I have attached a schematic of what we are thinking.

The end goal is best quality sound. according one of our sales advisors (friend working in the industry), we want the design that allows us to market with '5 Class D digital amplifers'. how many of STA339BW will we need or do we use another chip?

can you create three working models of this board? and suggest where to get manufactured?

we are planning to powering 5 speakers: 1 woofer, 2 mid range and 2 tweeters

the current ratings we are thinking are:
woofer 10W 6ohms
mid range 15W 8 ohms
tweeters 30W 8 ohms

will this work?

We value your suggestions and look forward to hear from you.

In the attached diagram, all items not coloured in blue need to be included in our circuit.

Thanks and Regards, Sorna
