Hello!
I'm newbie in electronics...
I want to build power amplifier with 2xTDA7293 or 2x LM3886 in parallel configuration, but, after long search i did'nt find PCB (one layer) for these aplication; i found only schematics and/or PCB dual layer.
Except this i have one question more...
For TDA7293 i found 2 different datasheets.... please check links:
http://www.st.com/stonline/products/literature/ds/6744/tda7293v.pdf
http://g.fondeville.free.fr/fichiers/TDA7293.pdf
Witch one is the good one? For modular aplication there are some diferences regardin conection between pins 2.3.4 and V-/GND for Tda7293 "slave"
Can sombody help me?

Ok, but they have different connections, both are correct?
I will check witch type are my TDA7293... i hope will work!
I just checked....
I have TDA7294V and....
Hmmm....
TDA7293V is included.... in both file!!!!!!!
And here is my confusion...
first file(from ST) have connected pins 2,3,4 from slave to -Vs but second file have connected 2, 3 to GND and only pin 4 on -Vs
I read some discussion about, and some electronists burned some TDA7393 if all pins are connected to -Vs.... and i don't want to have this "bad luck"
Sta da radim, onda?
Pomoc!

And, what i discovered more is:
file from www.st.com are from 2003, and second one if from 2000;
Hmm... i'm thinking on just one thing:
ST Microelectronics have changed(updated) schematic for TDA7293?
Or this is just one mistake? and the old file published is correct?
