about 50watt amplifier

50w amp

:D hi sabo,

here's some more amps you may want to consider:

LM2876 40w - can be powered by a single supply or dual supply. datasheet & application at;
**broken link removed**

STK4036 50w or STK4038 60w, circuittry and datasheet at
**broken link removed** :wink:
 
I think that TDA1514 from Philips has an output of 48W into 8 ohm load.
When I built this amplifier (two of them, actually), its sound was horrible. After a few experiments, I removed the bootstrap components and it worked like a charm :D

I've also built an amp using TDA7294 for a friend of mine. This IC rocks! And it's HOT. I mean...really really HOT. Adequate heatsink required. Preferably with a fan (thermally controlled). Although this IC has protections against overload, short-circuit, excessive temperature, etc. I still managed to blow up two of them :(

Indeed, but with a +/- 45V supply you can get up too 100Watt with it.
Got 4 of 'em running here like that.

4 x 100W on a 10 x 6cm pcb... :)
 
I used the same supply voltage (1V more or less).

4 x 100W on a 10 x 6cm pcb...
Talk about making things small :)

My PCB was approx 20 x 13 cm. It had 2 x 100W amps, stereo preamp with DC tone control and channel selector and two thermal sensors for fan control. I was soo happy when I built it and it worked. Hopefully it is still working :?

EDIT: Now I remebered that it also contained the power supply (on the same PCB)
 
If your interested in building a discrete amplifier this report might be of some use, it includes a design for a 50w bipolar amplifier. I've built it and know that it works.

Edit>> Sorry I think it might have been o big for the message board, i've put it on my webspace **broken link removed**
