Schematic Diagram USB Powered Audio Power Amplifier for PC

This audio power amplifier might be good solution to all of those who have PC with integrated sound card into motherboard. The main problem is that outputs of such sound cards are for active acoustic systems, this means that speakers must have power amplifier built in. If you decide to connect a headphones sometimes it might be not enough to provide required sound level.





If you are an electronics amateur, you can solve this very easily. You may build your simple power amplifier by using well known Philips operational amplifiers. Lets say we use TDA7053 amplifier. The TDA7053 is an integrated class-B stereo power amplifier in a 16-lead dual-in-line (DIL) plastic package. Which requires minimal amount of external parts. (IC Datasheet)
