Thanks Sonny. Hope they are of use to the community. They came out well, only one minor error, the IC2 silkscreen is missing its circular index in the lower left corner, which got left off the BrownDog master. They will probably fix it for the next batch.

Nice. Just put in my order. Trust OpAmp orientation is easy to sort by following the traces. Norman

The orientation of the text letters is correct, and both sides have an auxillary dot left of pad 1 in addition to the bigger circular index inside the rectangular chip outline.

Looks nice! Where does one get those single pins? Do they fit into machined turned hole sockets?

I use DIP8 pin to solder adaptors where the pins look thinner and more pointed. It is very easy to handle but with the plastic connecting the 8 pins, there is an extra 3 mm path to the PCB.

Greetings,

Eric

Those are machine press-fit pins. They are not intended for manual installation, as far as I know. The adapter is available without pins so you can install your own. Digikey sells pins if you are so inclined, however, I suggest getting adapters with pins installed.

I have tested the new BrownDog adapters with AD8610 and AD825 opamps. Both sound great. The AD8610 might be a bit more refined, however the AD825 puts out more current, which might be an issue if driving low impedance headphones directly, as in a CD player headphone output stage. Listen for yourself.

The AD825 max supply voltage is 18V, the AD8610 is 13.6V, so be sure to check the power supply if you are swapping opamps, there may be some 15V supplies out there.

Thumbs up Just installed these with 8610s

They are used as the I/V converters for my SACD player replacind opa2604s.

They worked perfectly. Delivery was super fast from BRN Dog and they are way cheaper than the LCaudio modules.
I didn't need bypass caps on my system.
