![]() ![]() ![]() I thought it would be good to share my project with the community… maybe someone finds it useful. ![]() Pin out on TDA7293 is tricky, so single-sided board is difficult to draw, and in the end contains more jumpers between lines than tracks… so, this one is made as double sided. the board layouts in the datasheet are flawed and little clumsy… we used them only as guidance with component arrangement on our PCB after few futile attempts to route the board with minimum jumper count. Our schematic is almost the same as in datasheet. I have been looking for a source of PCBs using parallel TDA7293s… there are not many out there that you can buy. Having built single chip amp and extensive listening TDA7293 is my favorites for IC power amp applications. This IC can run up to 100V, low distortion, and can easily be paralleled. This is when I and my friend John found the datasheet of TDA7293. I needed something as easy, but more powerful. As part of my home theater build, have decided to go for 3 way actives for front LCR… so, need to build 9 power amps for fronts and 8 amps for surrounds… to pair up with my Sherbourn PT-7020A pre/pro. ![]()
