DAC AK4499EX Project

[Alren]

2 or 4 layers, it is a technical subject.
But what we want to know, how it works compared to chips that we know for some time, like ESS9038Pro for example ?

If its like most of AKM versus ESS, AKM may tend to sound better and or may be preferred for professional music recording and reproduction purposes. However, a lot of the sound of a dac is dependent on the particular implementation more so than just the dac chip. Also could be that ESS has made some improvements in their new products with the Hyperstream 4 modulator. Don't know, haven't tried the new ones myself.

Có thể gửi tín hiệu I2S trực tiếp đến DAC PCB thông qua chân cắm và viết phần mềm dành riêng cho DAC cho tùy chọn này. Có nhiều giải pháp

DAC sẽ là full dual mono. Dạng tín hiệu I2S PCB đầu vào sẽ được gửi đến từng chanell DAC thông qua bộ cách ly kỹ thuật số. Một PCB DAC và một Bộ nguồn PCB - Một chanell. Đó là mục tiêu chính.

DAC sẽ có 6 đầu vào:
-USB
-3 x SPDIF
-2 x DẪN

CNC in progress

I am very interested in this project. Does anyone still have the PCB? I used to assemble ak4497EQ but now no ak4497 chip. I want to try ak4499Ex. Can someone help me

Iam from Vietnam. How much do you sell 1 piece? I sent you a message but no reply

 

[piglet11]

Chassis is finished
Now i have to prepare case for anodisation

 

[Toanhp]

Theo tôiyou should use 1 DAC board for 2 ak4499ex ic. Resistors and capacitors smd you should use type 1206 for easy soldering.

Hello piglet11!

Do you share BOM, drawings and gerber files? I would also like to make a personal DAC.

Hi @PaulREE
I do not share gerber files and schematics. Please, write PW if you want more details about PCB.

Hi @piglet11, can you send me a PM. I want to ask you about the project and the boards. Diyaudio says I am under moderation and can not send PM, yet. Thanks!

Hi @piglet11,

Do you still sell the boards for this DAC?

 

[Ghoostknight]

@piglet11 im also interested in schematics or pcbs

Singe chip stereo DAC project in progress

 

[Ghoostknight]

Any Infos on that? which opamps? will it be available soon?

I'm planning to use OPA1612 or OPA2828. I need 1–2 weeks to finish PCB. After this I will do the second version of digital selector.
PCB od DAC is 90x110 mm 4 layer.
