DAC-END R (ES9018) full assembled board - version 2

[audiodesign]

I have to specify that photos submitted today by Quanghao are related to the first prototype developed to check for any problems and fix them before production.

We need some more weeks to fix all and to design the new pcb with corrections.

Hi i i excuse, if i make some mistake.

You have always been a mistake. Did not your mother tell you ? 😀

No problem Vincent,I and Quanghao are not waiting without doing anything, we have produced the first prototype and now we are correcting the defects.
Soon will be 'made ​​the second prototype and each time the product becomes better.

Is everything ok Quanhao ? The Thyphon did not hit you ?

Is everything ok Quanhao ? The Thyphon did not hit you ?

things are going well, I am continuing corrected some small errors of layout, I will give the earliest information!

Thanks for the interest and enthusiasm, your for me!

Thank you!

Here's ES9018 DAC V2 structure. I invite you to watch!
Thank you

 

[quanghao]

This structure is designed DAC

This structure is designed DAC and the power supply, the output dac.

Invite you to watch it!

 

[Mas Penk]

Quanghao : I think I misread your item. Can I change the order?? I'd like to buy all items (item 1 to item 5) but I want to assemble them my self...

I just read that item 6 is an assembled unit.

A diamond buffer is the pilot of the passive I/V? The output stage is a single-ended mosfet?

yes, please see this schema!

 

[Erlend Sæterdal]

I like it 🙂

 

[quanghao]

About the new shunt for V2. change for the opam shunt in V1

HAK shunt regulator

and shunt regulator is designed to supply dac.

Here, together with the help and assistance of members Keantoken-a good one simulation and electronic theory, I have perfected it and call it the HAK-shunt!

Optical loss is very grateful for his help!

Please see the simulation results for the measurements!

Thank you!

Yep, that's what I said in post 77. So your order is really -
9. Mas Penk: DAC module + amanero + output stage + transformer + chassis
Corrected GB list in next post.
