[UPDATE] Loresek Discrete R-2R DAC Rev. B

17 Jul, 2019

Pada revisi Loresek Discrete R-2R DAC Rev. B ini, saya melakukan perombakan pada bagian power supply dari switching ke linier agar lebih bersih dalam meberikan asupan tenaga ke masing-masing IC TTL.

Bagian USB to i2s, saya menggunakan PCM2706 yang sebelumnya menggunakan Amanero. Ini saya lakukan agar tidak mubazir karna DAC hanya 16Bit dan juga untuk menghemat ruang karena modul USB to i2s yang menggunakan PCM2706 lebih kecil dan compact.

Data stream dari USB to i2s didelay untuk mendapatkan format EIAJ yang digunakan pada Discrete R-2R DAC ini.

Proyek DIY ini berdasar pada Simple R-2R DAC MK2 oleh Okiraku Audio www.easyaudiokit.com.
