AKM4399 dac

[play458]

Has anyone done this project or not
In Thailand, there are groups that are going to this project.
Do you think it would be worth a try. Give me some advise.
I have not been listening.

Thank you very much.

Since nobody seems to reply: I would go the ESS Sabre way.

Thank you. You all to read.
But I wanted to try. AK4399
Now, I just started doing this project, and then some.
I need a little time.
I will be watching the same show.

update my project
I'm waiting PCB
Thank you for visiting.

Given that the AK4399 produces a 2VRMS differential line-level output, I should think that perhaps the most critical stage will be your output buffer design and implementation. Particularly, should you want to produce a single-ended output from the AK4399 DAC's differential drive. An op-amp is probably the least risky solution to perform this function.

Should you want to stay away from op-amps then a transformer might immediately come to mind as the most elegant solution. However, while the AK4399 voltage outputs are rated to drive a 1k load, I believe that they also are only rated to drive up to 100pF of load capacitance. One meter of interconnect cable typically has more distributed capacitance than that, let alone including the input capacitance of the following component and the output transformer's parasitic winding capacitance. Which means that some form of active output buffer will most likely be necessary, even using an transformer.

Hello

Can you give us some details of your PCB

What is the blue PCB on the right picture ?

Thanks
Serge

Hello Sergelisses
A friend of mine is designing PCB for akm4399 Will bring in next time.
I take it out of the blue pcb from playstation2 it is modchip ....It fits akm4399
Was used to test akm4399 Just that.

็HELLO Ken Newton
Thanks for the suggestion I'm waiting PCB from my friend When it comes.
I will start to build AKM4399 My team has a lot of people.
We share the same job done.
Wait for a little one.Thank you for reading and commenting.

I was looking at adding the AKM4396 to the list of DACs I can use with my new SRC (WM8804 => SRC4192/SRCAD1896). I'll try the AKM4399 instead. Looks like a really nice DAC. Thanks!

My new SPDIF + SRC + DAC design platform

Best Regards,

Al

Is it a PCB with just the AKM 4399 or with the SPDIF receiver ,power supply ....
