Yeah....smoking Pioneer PD-8500 CD player+_VccL that goes to +_12V?!
I smell profume of smoke
@mikorist Based on the schematic we should have working DAC
For 63? I know only dac with digital filter. I can't imagine the NOS version. This is first version which I see for all my experience) It's very interesting the final result!I ordered a PCBs from JLCPCB. Wish me luck
I also ordered 1702 chips yesterday. The board will be ready to the next week and I start to search and buy the details. I was very impressed by 1704K Dac.
I used one from silicon labs for I2S signal, then removed it and the sound went slightly better (well, it is subjective). I did not notice any practical improvement == I will never use it again with DACMiro, what do you think about of galvanic isolation and separate feeding of the usb transport? Is it possible to get with my Amanero for example? I heard that is very positive for sound and many people use that. What does it take?
I am interested in how much current the DAC consumes (with AD1865), primarily the digital part with shift registers (+ 5V). At the moment it is very difficult to get adjustable version of the LT1963/3015 so I have to make an alternative power supply. For + 5V. That’s until I get LT regulators. I plan LP2950ACZ-5.0, (TO92 100mA), for +5V digital part. The analog part with OPA will be + -12V with LM2940 CT-12 regulators. OPA is Sparkos SS3601. The analog part of the AD1865 will be + -5V with LP2950ACZ-5.0 regulators. The transformer has two 12VAC secondaries, 16VA.

I only saw one man do this with PCM63P - Orronoco at blogspot point to point, but he didn't have JLSound or WaveIO, that means a lot.This is first version which I see for all my experience) It's very interesting the final result!

AD1865 is power friendly, very low current consumption.
25mA for digital part with shift registers is enough ... analog part +-30mA.
