By using this board, the overall power amplifier circuit can be greatly simplified by just interface the board to a VBE multiplier circuit and the power transistors. Most important of all, such built power amplifier is very robust and performance guaranteed, due to the superb audio specifications of LM4702. At a maximum supply voltage of +/-100V, LM4702 can allow an output swing of over 50Vrms and thus over 250W power when driving bipolar transistors in class AB mode !
PCB dimension : 120mm x 70mm
Board thickness : 1.6mm
Copper thickness : 75um( four times normal thickness !)
Supply voltage : +/-20V DC to +/-100V DC , 100mA
