TDA7293 100W RMS AMPLIFIER SCHEMATIC CIRCUIT DIAGRAM

Despite the TDA7293 small size, performance is very high amplifier integrated manufacturers ( ST Microelectronics ) “120volt 100watt DMOs audio amplifier with mute st-by,” says symmetric + -60v able to work with a total of 120 volts DC TDA7293 datasheet highest working voltj proposed by the Information + -50v The lowest operating voltage at the time of the 60v input when there was no audio signal + -12v. There is a diagram, pcb drawing and a list of materials.

Previously the TDA7293 100w DMOS audio amplifier integrated with the amplifier circuits were shared this circuit is considered the same with others, but the TDA7293 PCB design is very small and regular. In the circuit of the TDA7293 100W amplifier circuit, the DC diaphragm capacitors must be added in addition to the bridge diode
