Maybe I should go for chip amp!

[svsommer]

Hello
Possible you can tell me which parts I should go for
it will be used for HTPC 6 channel
Maybe around the TDA7294
Please refer to PCB layout
and component list
Many thanks

here are Schematic and PCB for TDA7294. hope these will help you.

how will this chip be in contrast to
lm3886?

Actually that PCB is for the TDA7293 which is very close to the TDA7294 but not exactly , the TDA7293 is about the same price as the 7294 but marginally better .....


Well the TDA7293/7294 are Mosfet chip amps where the LM3886 are BJT , I find the LM3886 to be a more clean and clinical sound were there TDA7293 is more musical , also the LM3886 sounds awefull when it clips but the TDA7293 sounds not so bad when it clips ...... the TDA chips also have a bit more output power ....

Hi MINION,
I studied the datasheet of TDA7293 and 94. I didnt find any difference in CHIPs inside circuit and also in external component circuit. Difference found only in output power and supply voltage rating. Did you find any other differences?

The TDA7293 needs Pin 5 tied to the Positive power rail .....

There is another interesting difference - the ability to parallel 7293s without needing any sharing resistors. They have a master/slave facility. So higher powers are eminently feasible.

Hi all,
I am attaching some files for TDA7294 PCB design. I got them from someone on internet. I didnt checked it at all. Check this....

how much difference is there really
in all pcb I find on the Internet?

Why don't you build it on a pref board instead it is easier and you wull get to do some real DIYing instead of trying to make from a PCB done by someone else.Try it it's so much fun on a pref board.
