Okay...okay

I'm a bit disappointed that the v1.2 PCB does not have DIP op amp sockets.

The better op amps nowaday are mostly only available in single channel SOIC form (eg. LME49710, AD797...), which can be converted to dual channel DIP easily with an adaptor. Without op amp socket, it is almost impossible to use these single channel op amp in this DAC, significantly hinder the flexibility of op amp usage.

For DIY, DIP op amp sockets is the way to go.

Okay for IV stage opamps except for the avcc buffer I will put back the DIP+SOIC option. I will put the new updated board photo link tomorrow.

Thanks syllable.
The new ADM7150 option is great.

Hi, I dont havr accces to the photos, can someone post them? Please

 

[cristi289]

OK...

 

[cloudalmasai]

OK...

Thanks

Hi syllable, I have some questions:

- This dac can work in synchronous mode?

- Its posiblly to add a basic 5V power supply in the empty space of the pcb? for powering a raspberry pi or beaglebone black in a very small footprint.

- Can you repost the photos of the dual-mono dac from before?

Thanks

 

[syllable]

By default the DAC works in asynchronous but it does support synchronous mode also. On the right bottom corner there is a regulator reg9 its a 5v regulator it can be used. The ES9018 dual mono DAC I can offer that if there is a considerable interest. The photo I posted earlier was of a old version of dualmono but I do have a recently updated one which has again ADM and tps based PS and inputs similar to k2m board. I will post photo link of the old and updated DM boards tomorrow.

Here is the DM dac photos, i can offer this only if there is a considerable interest and not for one or two people and should not be coupled with this GB.

TPS regs for me.

I will be good that if there is a dedicated ADP 3.3v reg for XMOS or Amanero, to eliminate the noisy USB power.

Also what kind of oscillator are we looking at here ? Crystek 950 or NDK ?

 

[syllable]

Obviously you cannot get the Crystek 950 for $5. Crystek 950 costs around $28+shipping. You can use it if you want. I have already mentioned the crystal oscillator in the bom posted earlier, kly refer that. I will place a dedicated 3.3v ADP on the bottom right corner.
