TAS5630 D-Class build

[judtoff]

I think I'm going to try doing a similar design. I am planning on using a pair of these chips to make a pair of active monitors. Did you etch your own PCB? I will probably use BatchPCB from Sparkfun.

Edit,

I noticed you posted the eagle .brd file, any chance you'd post the schematic too?
I plan on having an active lowpass and highpass on each of my boards so I'll need to change the schematic a lot.
Or does anyone know where to get the component library for this chip, that's all I really need.

Thanks,

If anyone needs the library file.
Sorry about the double post, it won't let me edit my previous post again.

Can someone post 2 channel version of this board ? I installed Eagle, but it's a little confusing for me, because I'm using Accel Pcad for PCB drawing.

Well you can print it out and cut away the 2 other amps if its a problem, as the design is scalable to any number of channels by copy pasting more amps down.

I didn't think so many of you would want to make the PCB.

btw yes i make my PCBs at home using the UV process.

I really recommend you guys use this website for custom PCBs.
BatchPCB - Home
It's only $2.50/Sq in for a double sided board.
It would reduce the chances of having solder flow where it doesn't belong.
And then you could have a proper ground plane.

Any chance you'll post the schematic file? I know I'm lazy lol.

The design is probably 100% what TI show on their website for how to use the TAS5630. The only thing you need to do is change the input filter to something you require.

 

[berni8k]

Yes its mostly built to the schematic from the datasheet, also i didn't even draw the datasheet in eagle, as its so simple i just worked from scratch and having the datasheet open next to eagle

 

[judtoff]

Alright fair enough.
It's not that I can't do it, it's that it is a royal pita with this laptops trackpad.
If I had the scematic file I'd just have to add my input filters.
Time to install eagle on my desktop.

The second PCB already manufactured,Use TAS5630DKD,More stable excellent sound.If you love it please connect me by mail:authlxl@163.com. picture upload

 

[authlxl]

The second version PCB have manufactured,use TAS5630 DKD

 

[authlxl]

I finally finished this module,with TI TAS5615,the module picture i'll upload next, I found some bugs in this chip,Friend use this chip are carefully,
First +12v power must constant with +50v power supply ,if +50v power on +12v power down,the chip always burn when power on next time.
Second the balance input OP parts must have good decouple，at signal input port ,sensitive is so high ,DC voltage also on it ,suddenness always here。
NOW，I hearing excellent music with this amp module ,short out， over temperature，heatsink design.all done!

An externally hosted image should be here but it was not working when we last tested it.

VOLUME：250mm（L)*65mm(W)*35MM(H)

POWER SUPPLY： 80V~265V AC 50Hz/60Hz GLOBE SOURCE SUPPLY

The second version module have finished,upload picture here .

 

[authlxl]

It's powerful chip,I have used it on my product.

Tas5630+smps module

Some module for my friends,send pic here.

Authxl -- some things I can't quite figure from your data sheet- it says your amplifier can produce 150W per channel. Is the power limit (150W rather than 300W) because of the power supply limitation?

And can it be configured for 'PBTL' mode? If it can what power could it do for the single channel then? (would it be 300W for 4 ohm, 150W for 8 ohms?)

excellent sound output

Output sound good at this situation througn many times test,Output signal THD≥10% When power out 300W/4Ω，for professional product it's incompatible THD so high,driver speaker will be burned.Tas5630 works unstabitily When power out 300W/4Ω，It's economic with this SMPS .It is strength for 90~250V ac input,Global source supply.

I'm not suggest use PBTL mode for sound amp,I try it many times,We not satisfy with it.

compare with other class d amp chip,TAS5630 have better sound.

I have use it in combo professional mixer and active speaker,operation is very stable，excellent soud .

constant-voltage audio power amplifier use tas5630

Today ,friends ask me can you make amp by TAS5630 for constant-voltage audios system,It's easy,you can change output inductor as autotransformer，and use depth feedback mix with input singal.I have made class d amp for PA system 75v and 100v system like YAMAHA four channel products.you can down load schematic from yorkville website.

 

[Eva]

I think 100V line amplifiers can't be done with TAS5630 without a separate transformer, output coil can't be turned into an autotransformer.

 

[authlxl]

Hi,EVA,It can up voltage to 100v line amplifier,you can try it by toroial ring (high-frequency iron dust core ).

Here is the final version of the PCB that uses ground and power planes on the 2nd layer.
