As the title says....The TDA7293 is what I need a board for, but it will be stereo so for two ICs.
The board Dims are:
101mm x 152mm
But not strictly so...
In the following I will show a few different schematics which will comprise the different sections of the total circuit and let you know what spec component(s) used. I will give every detail needed...I also may have one or two questions on ideas.
The pics are in the attatched below
NOTES: I realize it is smart to have some protection circuitry, and also have different capacitors and rectifiers per unit(2 ICs, 1 opamp) but i'd like to start here and go with it and then maybe later redo a design when I learn how to use those CAD programs...
Can I use two "simple switcher" circuits to reduce rails for the op amp? I figure a NEG rail is the same thing practically as a POS rail but in a different location in a dual supply right? current travels the same way as the pos rail but different phase so it should work?
Btw, the SEC windings are +/-42V raw before rectification..Will rectification take me too high for the ICs? It says it can withstand +/-60V at idle.
Also, in the main IC schematic, the shown 1mF power supply Caps are the ones shown in the main power supply schematic except the main schematic shows 6.8mF but I meant I am going with 8.2mF caps not 6.8...
Thankyou for help...
