I also like the two on one board idea for stereo - will this then include master/slave sync connections pre-wired between the two boards? Or is it that dual mono PBTL does not need master/slave clock sync?
You will have to select master/slave/gain resistor configuration and connect the two points using a jumper...I will have to search through 3116 thread for R/C combination that actually worked...TI sheets were incorrect.
Owners can experiment with master slave configurations.

Hi Dug,
I hope you can finalise the price for these options and place it on the first page of this thread.
I prefer the basic kit with IC soldered.
thanks

Dug,
For the parts in the kit to get a sound, will these be of very high quality? If not, is it possible to get a list that has a corresponding recommended part? I have no knowledge as to what is brand to use in order to get HQ, I would not know head from the tail. I already tried several 3116 board and all of them needs modification, which I do not know where to begin.
Thanks!

I admit I am getting confused - for one stereo amp I'll need one board, correct? Price per board will be $8,-CDN, plus $22,-CDN for the chi,p plus $9 CDN for soldering, plus postage, correct?
Cheers,
The tpa3116D2DAD is a stereo IC (two channels) that each channel is a BTL.
There is an option of combining the channels in such a way as to double to output current capability. This configuration is called PBTL. (Parallel Bridge Tied Load)
The board I have made is a PBTL board.
Yes, you would need two for stereo.

Good idea to put all on the first post...I had forgot about that function.

They will not be exotic "audiophile" parts.
They will correspond to the types of components suggested in the data sheet and/or ap note (and my preference.)
As a minimum there will be a "recommended" parts list with bare board purchase.
Parts will be available from Digi-Key and depending on how energetic I feel I might include parts available from Newark (Farnell) or Mouser.
To begin, either build the board and listen to it while reading the posts in " http://www.diyaudio.com/forums/class-d/237086-tpa3116d2-amp-372.html#post3985800 " or read the posts first and decide what direction you want to try and then build the board.
Make one change at a time...just like true experimentation.
Thanks for the efforts DUG. No offence but the explanation in this thread is very confusing for a newbie like me. I am sure it is pretty clear for most DIYers. I know it is a DIY forum and maybe I should not complain but I wish the options and what parts people can/will get would be more clear. Yes, I also want to order but do not know what to order. Again, thanks for your efforts DUG.
I am confused as well, the price for the IC and soldered is 7CDN or 7 for IC and 7 for solder?
$8CDN for the bare board
$7CDN for the IC supplied
$7CDN for the soldering
So a board with the IC installed is $22CDN plus shipping.

Yes, it is a little disjointed.
To All:
Look for a revision of the first post later tonight.

OK, I was confused on this. Please make my order for 316 chips supplies but not soldered. Every $ counts!!
Hi Doug,
Is there a heat slug on the undersurface of the TPA 3116 chip that need to be soldered to the pcb as heat sink?
thanks
kp93300
The TPA3118 has the pad underneath.
Surprisingly lower thermal impedance than the 3116. I guess you have to choose between 0.3K/W to the board(3118) or 1.2K/W to a heatsink (3116)
This board will accept either.
What does "get it running" level mean? Volume pot, enclosure,etc?
No volume pot, no power supply, no speakers, no speaker cables, no source connectors, no enclosure, no mounting hardware.
Doug

I thought you also included speakers and one with high sensitivity too, no? Joking of course!
Good answer I asked for details before and you gave it more than enough answer for what is not included
So, really what we will get is like YJ Blue/Black board if we want "get it running" level, correct?
