Bittonic?

Mikael Abdellah · 14th August 2007, 11:39 AM

I have a couple of small class d amplifier boards I purchased as samples a couple of months ago. On the back of the pcb there is a small SMD chip that says "Bittonic BD3688S". This particular module is a 2.1 amp and I am pretty sure it is basically 2 stereo amplifiers with one of them bridged. I can't find any information whatsoever about bittonic. Has anyone heard of them before?

Bittonic? boh!
Maybe a custom device (improbable), or a common IC remarked with another name...

Hi Mikael. I've never heard of that name either. Chances are it is a custom chip of foreign origin since there is basically no info available. Where/Who did you purchase the class d amplifier boards from and what are they called?

Can you post a pic?

I will try to post pics and more info today. I still haven't found my digital camera, that's why I have not posted it already.
