Hi XTAL,
You can find o interesting report in the
ELEKTOR review, Spanish versión are the
numbers Nº:235, 236,237 but I think that you can to intoduce in the official web of elektor but I don´t sure if the elektor have a www page.
If you have any problems about it, I can sending to you the Schematics, but the article are in spanish.

Hi Jesus,

sorry to disturb you one more time, but this article seems very interesting to me. I am right now stating to develop a DAC with CS8420+DF1704+PCM1704 and it can help me. I have no problem in reading spanish.

My e-mail is: joao.yazbek@uol.com.br

Thanks in advance...

Joao

check the application notes for the DF and PCM parts - There is a demo board available for $399 US that will allow you to experiment with various modes. The app note for the board includes a schematic and board layout should you decide to DIY it.

Link to app note: http://focus.ti.com/lit/ug/sbau013/sbau013.pdf

several language options are available if you go to ti's main site - search for DEM-DAI1704 for the board info.

It's funny how so many circuits you find on the web are just minor (if that much) variatons on application note designs. I never saw teh Elektor design so I am not commenting on that.

Hi Jesus,

My mail box has 20 Mbytes, I could not understand why it refused your e-mail. If you can try it again, send me in two or three separate files, I think that it will work fine.


Again, thanks for the attention.

Default Don't use CS8420

CS8420 and nearly all ASRC is rubbish, sounds bad.
Use AD826 and LT1027 as the power supply of PCM1704, which really sounds good.
Regards,
AD1865
