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

[Brijac]

It's all in good spirit, at least from my side 😇

 

[Vunce]

You spicy Serbs🌶

You should try soviet red MF resistors.... 🙂

or Tesla with gold pins...

I have a lot of red ones from the USSR, but I don't know if they are metal film. Tolerance is 2%.

Datasheet says they are little better than modern chinese carbon film resistors ( including also 3-5W carbon film res. from Koa Speer ).


🙂

 

[NIXIE62]

But the datasheet never says what it sounds like.

 

[krca45]

For sure it does not - will try them and others soon with dip switch. So I'll let you know if there is something interesting.

To be at least nominally on subject - will etch tomorrow / day after - Nixie's regulator boards.

LM1117T ones for JLSound pcb + some other reg boards.

From page 2 - it's a long read😉

Regarding those fake PCM1702 I got the money back.

New message from: foreverwin2023 (31)​

sorry for this situation i have canceled the order and fully refund you Please take a look best regards​

What should I get on ebay now? Say I skip the SMD PCM1702 and only look at the DIP versions? And for that there is also a PCM1702 to PCM63P adapter.

Why not try AD1862? It has a reliable source. Plus I want to hear side by side with PCM 63 - to hear the difference.😀

 

[NIXIE62]

I have completed PCBs for AD1865 and PCM63, I can't now include AD1862 in the whole story. I will now deal with the power supplies for these two PCBs. I finally got all the parts.

If you change your mind, we can order a PCBs together 🤣

 

[NIXIE62]

No chance. 🙄

Hey guys,
when you order PCBs what kind of finishing do you usually prefer from soldering point of view?
Does it worth to order with the ENIG finishing?

 

[Brijac]

HASL with lead. ENIG is cool if you plan to have your boards sit on a shelf for decades 🙂

Hi, there! Now I have the third DAC (AD1865N-J). There was not enough SMD's 😀
Now I need he PSU for him but I don't understand about 5V (+ and ground) - were I can find him if the all PSU with a third point?🙄
I saw a new PSU from Miro - are they also good like old versions?

 

[jimk04]

Just use 'half' of a PSU 1 or 2

 

[sworder84]

What about the rest?
Half of a PSU will fit into the analog part and what do I feed the digital?

 

[jimk04]

Just the positive half of the 5v output.. ignore the -5 output .

 

[sworder84]

Is that allowed? I mean the voltage will be no longer 5V.
