Build a 15W Bridge Audio Amplifier Circuit based TDA2002 . 15W bridge audio amplifier circuit which use 2 pieces of TDA2002. This is audio amplifier for general, work with a single power supply. Use 2A power supply transformer for maximum performance and heatsink should be used to keep the IC from overheating. Build a 15W Bridge Audio Amplifier Circuit based TDA2002 Component part list: R1-5 = 2.7? R2 = 100? R3-4 = 2.2? R6 = 220? R7 = 1M? TR1 = 100K? trimmer C1-9 = 10uF/16V C2-8 = 220uF/16V C3-4-5-7 = 100nF/63V C6=470uF/25V IC1-2=TDA2002 Lsp = 4 – 8?/40W Loundspeaker

When I was in the preliminary stages of bridge design, I also had repeated failures. I had circuits blowing up. I had circuits just not working, no matter what. I’ve written on my blog about one such experience of mine. You can read it here: http://www.blogspot.com/2016/10/magic-of-knowledge.html In this article, I’ll talk about the first things you should do if your attempts at designing a bridge circuit have gone up in smoke or if you’re designing a bridge circuit and want to ensure everything has been done properly. Another thing I should mention is ...
