100W Power Amplifier TDA7294 in SMD PCB

 

Elcircuit will share a fixed and tested PCB layout for the TDA7294 power amplifier or you can also use the TDA7293, this power amplifier PCB uses SMD and throughole supporting components. by using SMD components the PCB dimensions can be smaller, this PCB has quite small and simple dimensions with a length of 4.6cm and a width of 2.7cm. quite small for the size of the TDA7294 power amplifier PCB. For the power amplifier schematic according to the PCB, see the image below.

Schematic Power Amplifier TDA7294 SMD

In the schematic above, it is quite simple, using the schematic according to the datasheet, and it has been fixed and tested to produce power according to the datasheet. For IC use, use the original so that the results can be maximum and with a minimum power supply of +30 0 -30VDC, a maximum of +40 0 -40 VDC for maximum results and safer at a voltage of +35 0 -35VDC. use at least 3A for one amplifier kit or 5A for 2 amplifier kits.

TDA7294 Watt Power Load Tested at 4 ohm 

In the picture above is a summary of the load power using a 4-ohm resistor load, the output voltage is 20.49V with a current of 4.8A so the total power is 98.35W RMS, yes you could just say 100W, for use this amplifier is very suitable for indoor use. For outdoor use, it is usually used on 2 way speakers to control the tweeter speakers.
