circuit power amplifier of 18 watts RMS in bridge using tda2009

TDA2009 is an audio power amplifier double hi-fi in multiwatt package, especially developed for applications of high quality stereo. That application is the amplification in bridge, where it is used the two amplifiers interns of the tda2009. The good of the series of circuits integrated tda is that are component electronic easy to find at the electronics stores. Although some can find the potency of 18 watts little rms, be sure that many of those audio equipments industrialized they use that type of integrated circuit and they speak in potencies of up to 100 watts. That circuit supplies a potency even considerable to hear music.
