Low cost ES9018 DAC board GB

[rredline]

Check out the updated board, it now uses ADM7150 regulator as an option as well as TPS7A47 symmetrical power supply for the opamps.

That's a nice board, when we start syllable?

 

[Ryssen]

Could the regulators be presoldered to?

Could the regulators be presoldered to?

Yes, if you want.

 

[cristi289]

Syllable, now, with new regulators and soldered too, the price will suffer any modification?

 

[syllable]

If you use adm7150 yes there will be small increase in total cost.

 

[cristi289]

Ok, I wait a sign from you when we start and how bigger it will be the final price.
Best regards,
Cristi.

 

[Jackal29a]

Syllable, I'm getting a no permissions message when I try to access tha latest links you posted so I can't see the images. Can you please fix them?

 

[cristi289]

Check this attachment ...

 

[syllable]

Total cost at digikey will come to around $120 if you are going to use Adm and tps . I will offer gold immersion pcb for this project at the same price.

[cloudalmasai]

Hi syllable, what is the total cost of the board with the dac, oscillator an TPS7A47 regs pre-soldered? Thanks.

 

[syllable]

Board $20, oscillator v$5, IC $20, if want the TPS regs soldered $17, you can also use LM based symmetrical PS if you want it is cheaper. You can also upgrade to ADM later even after populating the ADP if you want. Sounds damn good even with ADP and LM based PS.

change to pre-soldered.
Thanks

 

[TNT]

Well I set my self up for DAC on THIS GB.

Ryssen, how many DACs do you own now The search never ends...

 

[dady]

One board +one chip pre-soldered+oscillator.

Ryssen, how many DACs do you own now The search never ends...

Well lets see now,theres the AK4396 and CS4398 and ES9023 (3 of them) and AD 1865 (that never got finnished..)and one ES9018 experimental board that I am going to use with the tube unballancer...So there´s a whole bunch of them..

I use the one ES9023 as Bas/mid and the CS4398 at the mid/treble and one ES9023 as SUB......
