Balanced DAC I2S interface project

The OPA861 based output stage for TDA1541A, as used in the AYA II DAC, was posted here one month ago and, according to feedback, authentic and ambitious DIY spirit is still around.

This time I am reposting another old article, which was once available at pedjarogic.com. It shows how to make I2S channel and phase splitter for balanced DAC based on CS841x and two TDA1541(A). The same circuit will work in any other balanced DAC that needs such a splitter, and uses 64 bit frame I2S. The PDF file is mostly in its original form, with minor text edits for clarity.

The circuit is explained in detail, and is well tested and proven during these years. However I can not provide any additional support for this kind of open source projects.

 You must be to download this PDF.
