USB Portundan Ses Çıkışı projesi USB Audio DAC Bilgisayarın USB Portunu kullanarak Ses çıkışı alabilirsiniz PCM2902 ve LP2951CM kullanılmış kaynak Eagle Şema ve PCB Dosyaları var PCM2902.
Circuit includes DAC, ADC, SPDIF output, input and HID part with 3 buttons for MUTE, VOL+ and VOL-. I used only DAC part. Other parts are not used. For high quality playback is needed to use external low-drop voltage stabiliser for DAC part. I used LP2951CM which was available at local store. Output voltage is set to about 3.7V with two resistors. Circuit board is designed regarding to good ground placement and separating of analog and digital ground. These ground are connected in one point at USB connector.
