Testing the $11 TDA7294 Amp Board Genuine IC or Fake | Genuine IC Cost $9.89 each

$11.53 TDA7294 Amp Board Genuine IC or Fake | Genuine IC Cost $9.89 each

The amp is tested on how much power it can do before clipping with 8 ohms 6 ohms and 4 ohms load. Distortion is also shown for each test.


Results | Max output before clipping

8 Ohms Load
Max Voltage Output Peak to Peak - 73.6V
Distortion - 0.062%
Power Output RMS - 84.6 Watts

6 Ohms Load
Max Voltage Output Peak to Peak - 64.8V
Distortion - 0.06%
Power Output RMS - 87.5 Watts

4 Ohms Load
Max Voltage Output Peak to Peak - 54V
Distortion - 0.064%
Power Output RMS - 91 Watts

The specs for the TDA 7294 IC shows that it can do 70 Watts RMS at 8Ω 6Ω and 4Ω load while the amp board with the fake IC can only do about 53 Watts RMS, check it here    • $3.5 100W Fake TDA7294 Amplifier Boar...  .

The results speaks for itself, the output power of the board has meet what was in the datasheet and even had a lower distortion, thus can say that the IC used in this board is genuine and this is a really good price considering you get the fully assembled board while the genuine IC alone is around $9.89 each + shipping cost (Price based on Mouser 13/02/2024).
