A simple Hi-Fi amplifier which is built using a single TDA2050 chip. The circuit is very simple and can easily be constructed on a perfboard or point-to-point so it makes for a good first DIY Audio Project. The power output is about 25W into 8 ohms. The performance of the amplifier is very good (see datasheet) and the fidelity is also very good – comparable or better than most Hi-Fi Class-AB amps which often cost much more.
