USB DAC PCB

[PeterWurmsdobler]

Hello,

 

As indicated in the subject, I am looking for a USB DAC as a single PCB, i.e. a module that can be integrated. There are plenty of stand alone USB DAC devices on the market, and I would like to buy a module that is in such devices. This module (PCB) should provide:

 

- 5V external power input (not USB powered),

- Convert stereo up to 24bit@96kHz

- Volume control through USB endpoint

- EnableOutput controlled through USB

 

I could imagine an implementation that uses a USB streaming controller in conjunction with a DAC and a Programmable Gain Amplifier. Is there anything on the market that would fulfil my requirements?

 

Cheers,

peter

There are DIY USB DAC kits.

Hello and thanks,

 

HiFiDIY have nearly what I am after, if I can purchase the populated PCB without the case. Also I do not need the volume control. I would rather prefer a PGA controlled by USB. Any idea of a DIY kit that offers this feature?

 

Cheers,

Not exactly what you are looking for ... but you can buy the HiFi DIY Aune DAC pre-built. Costs around £100 off eBay IIRC. Then you could adapt it for your needs.

 

Another possibility would be to use something like the Altmann Attraction DAC combined with (for example) the M2Tech HiFace ... build them both into a case and Bob's your mother's brother - you didn't give any indication of price you were willing to pay.

Hello and thanks for the hints.

 

Well, if I have to buy and modify a kit, I would rather prefer to make my own PCB, which is exactly what I wanted to avoid.

 

As far as the price is concerned, I would be prepared to pay £50 for a populated PCB that meets my requirement (5V and USB in, stereo audio out, SNR ~100dB, volume control through USB, logical output when switched on).

 

Cheers,
