My
brother and I have built a new no oversampling DAC, based on the Philips
TDA1543 DAC chip, with passive I/V conversion, no filtering after the
digital to analog conversion. Our DAC is inspired by the Nonoz III dac,
check out the links page for a link to Nonoz III dac with schematics. We
think it has turned out to be a very successful project, with an exciting
new enclosure design. As for the sound we are very pleased with our new
little DAC.
The DAC can be remote controlled with a Sony compatible IR remote,
through a embeded IR learn function or our IR datalink software.
Below
you can see some pictures of our design (click on the picture to enlarge

We could not get the CS8412 in DIP house, so we decided to build a small
converter pcb. |
