New Version 2025 compatible with TDA5708 en TDA8808<\/p>\n

\"\"<\/p>\n

I designed a small SAA7220 adapter board, \u00a0it adds a coax digital input on a SAA7220 Chipset CD-player, so it can used as a DAC when the cd player is not playing . When the CD player is started the spdif input will switch off and the cd player is working as normal. The spdif interface is based on a WM8804. and can be used at \u00a032 , 44.1 and 48 kHz.<\/p>\n

The idea started on MFBfreak.com<\/a><\/span><\/p>\n
