How to Make 170W High Power Audio Amplifier using TDA7294



Published
In this video, we are going to make a TDA7294 Based 170W High Power Audio Amplifier. The TDA7294 IC is a great sounding amplifier IC with low cost. Furthermore, it has a ton of power handling capacity. Theoretically, 100W to be exact, and for this Audio Amplifier tutorial, we are going to use two of those TDA7294 ICs in a bridge configuration to build an even more powerful amp that can handle up to 170W of RMS power and we will walk you through the building process and first, we will show you how you can calculate the voltage and current that is required for your power supply, then we will find how to get a proper heatsink as per the thermal data given in the datasheet of the TDA7294 IC and finally, we will discuss how you can change the gain of the amplifier by tweaking the values of the circuit.
