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

Hi diyiggy,

sure I have noticed your posts a 100 times and still enjoy your special sense of humor!
I have noticed correctly, the text on the DAC board you sent, is the same as on Miro's board which in fact is on page 1 of Miros legendary thread.
 
All tribute to Miro, He does have great sense of humor and he is a very inspiring guy not only on the technical. I DO like his philosophy; remind me the slow food movement born in Italy.

The gerbers I gave is exactly all HIS front end and I just tweaked all the output stage to give more freedom on 3 things that migth be important or not according everyone needs:

: it is made for very fast op amp for soic smd size. (and has tricks about that in the layout while using 2 layers)
  • it allows you to choose the voltage you need according the op amps you want to try (some needs different voltage than 12V common plug of miro's board)
  • it is a two stage op amps for the few that needs a further buffer stages some op amps for I/V could be weak here and/or for headphone lovers that needs high current voltahe folllower >150 mA a standalone chip for I/V doesn't allow (for many) ! For instance there are "plenty" 200 mA and more op amps for difficult cans.
  • It is anti coldpissssss spirit as I don't advice special op amps end of the game although I had an idea when making it.

That's all, it is not better than miro1360, it is a tribute to his work and a modest contribution. I do have a 4 layers options that is enterily layout remade but this one is not shared and I wonder if it could be solded for a small fees, but it has nothing to see here in this good thread. 🙂

Edit : I dunno my special humor migth have some cultural limitation in some countries due to the strong anbiant moral wokism credo of: "all-is-fine-show must-goes-on,-never-discuss-of salt-grain-in-the-machin" phenomology typed; but it is never made as a mechant behavior 😉. See itmore as "when everyone agree, let's call that dictature" 🙂 🥷
:dead::yikes::clown:
Am I not a french deaf rooster with strong intolerable behavior, am I? 😉 !

@miro1360 check your coffee stash 😉 Your boards are in, just tiny things, so simple. Also thanks to the mighty @prasi, always excellent work from that man.

If anyone is interested in trying the AD1865R SOIC chip then I have a few adapters spare, also some simple AD1865 UFL connector DAC boards, quite specific but can be used with the JLSounds V3 module.

AD1865R SOIC is much cheaper and easier to find.

@Legend Electronics is a solid vendor, excellent packing and quick shipping for AD1865R chips.
