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

Hi guys and gals.
I've asked in Ian's thread but to no avail so I ask here about 'snaps' and 'pops' between tracks. Using Ian's Fifo with both XOs populated. Rpi set to no oversampling. I get awful pops and snaps between tracks. I fear for the tweeters.
If I force an oversample to use just one clock it's the same.
Any advice on this?
Thanks
 
Hi, I want to build the PCM63P dac version. I will be feeding it with a WIIM pro that only has coaxial and spdif outputs. Any suggestions on what board for the IS2 convertor? The JLsounds board is usb only from what I can see. So I need a board that accepts coaxial or Spdif and will work with the PCM63P dac. Thanks
 
Thank you zoom777. I cant find that model on ebay so looking for a solution there. Would this work? Do the LED screens cause any kind of interference or noise problems? Is the WM8805 better than the ak4118.

That adapter was whipped up specifically to properly convert the dual OPA1656 opamp for single opamp usage. Since then the single OPA1655 was released, just use a standard SOIC8 to DIP8 adapter and no additional parts are needed.

But, I believe the resistors are 0805 size and the cap is 0603. Just double check that with the supporting documentation in this thread.

Hello fellow DAC builders,
I have need of a 2 genuine AD1862 N chips. I have a PM into one member who had some for sale awhile ago, but would like to ask here if anyone here in the US or Canada would have a spare pair. Thank you for your consideration.
Regards,
MM
