Topless Photos (of equipment)

Sure looks like an all through hole design, there probably won't be any chips on the underside.

Can you explain? Actually I should re phrase, shouldn't there be a BB chip?

I am not familiar with the product, so I can't comment on the IC complement. I am very familiar with electronic assembly; through hole cost more than surface mount, both together cost the most of all. The soldering process for the two mounting techniques are radically different. Most designers will not mix the two technologies without a very good reason.

The side of the PCB that's is visible shows not even a single surface mount part and the trace width and spacings are normal for through hole. A surface mount PCB design tool will default to much smaller trace details due to increased part density. This doesn't make it impossible that there are no surface mount parts on the other side, just unlikely.

Texas Instruments bought Burr-Brown some time ago, I assume the Burr-Brown logo is no longer in use.

Hope that helps.
