DAC AD1862: Almost THT, I2S input, NOS, R-2R

[Michelag]

Guys, why now the moode with amanero clone is giving me a cracking and popping sound? While on USB out of phone is perfect... Settings are i2s DAC (tested all the 3 choices) and amanero combo as driver... Can't find a reasonable reason for that... Perhaps something is wrong in some interface?

Have you connected Amanero to your phone?

 

[Michelag]

Yes, works fine

 

[NIXIE62]

And the problems caused by being connected to a PC?

 

[Michelag]

Nope, raspberry with Moode audio installed

 

[NIXIE62]

I wouldn't know about that. I installed 3-4 of those Amanero clones, never had any problems, but I only use PC and Win10. Some others use Linux, without problems.

There are other types; 1SMB5934BT3G, 1SMB5934B-W, 1PGSMB5934,CZRB5359B-HF..... Calculate that this diode will have about 300mW of dissipation, so give it a little more copper surface area.
As for 10nF/400V, you have FCN1913G103J-E3 and SMDTG02100TA00MQ00.
It would be a good idea to put a decoupling capacitor at the regulator input, for example 0.1uF/400V (CB162I0104KBC). You can make the PCB so that the capacitors are TH as well as the power resistor and everything else is SMD.

here we go :
big resistor and 2 capacitors are now THT, diode corrected, added decoupling cap

How do you connect

Wonderful!

@6L6 can you please repost the pic? I am also in the works for a D1. Some pics will drive me towards the finishing line. 😀

Reload the page?

The photo is visible on my browser, and it’s even visible in your post - in the quote of the post of the original photo…

🙂 🙂 🙂

@6L6 I can see this one now, not the earlier one posted. Nice work there! My parts from Digikey is on the way. I am getting excited by looking at the pic you posted. 🙏

Reload the page?

try from another comp, you'll see

ahem, you'll not

 

[6L6]

I can see it on my computer, my phone, and my tablet…



Anyway, for the sake of thoroughness:

You are possibly the only one who can see it. 😀 😀 😀

This is what we see:


Anyway, the last one works.

The above pic works nicely

This D1 uses 2SK2013 in place of the IRF510, they have a different average Vgs and the stock resistor/pot value wasn’t able to pull the gate to zero, an adjustment of the resistor between ground and the pot from 10K to 4K7 gave the needed adjustment to achieve 0vdc on the input.

Sounds beautiful.

Thanks to @Sorenm for the PCB. 👏

 

[zoom777]

Any reason why use 2sk2013 instead of irf510? Or is it because you have the 2sk2013 in your drawer? @6L6

 

[6L6]

Exactly that. I have a small amount of K2013/J313 and this is the perfect place to use them.
