TDA7293, despite the small performance too high an amplifier integrated manufacturers (ST Microelectronics) “120volt 100watt DMOs audio amplifier with mute st-by,” says symmetric +-60V 120-volt dc able to work with TDA7293 datasheet information according to the maximum recommended working voltj the +-50v 60V input audio signal when it is not in the lowest operating voltage +-12V have. Circuit diagram of the PCB drawing and material list.
Earlier TDA7293 DMOS audio amplifier 100w amplifier integrated circuits made with the same count was shared with the others, but this circuit TDA7293 PCB design was quite small and tidy. TDA7293 amplifier circuit 100W DC filter capacitors in printed circuit there should be added in addition to the diode bridge
