Power Amplifier based tda7294 from ST microeletronics, you can gain power up to 100W in a single chip, for stereo unit, use similar two circuits. This circuit is based on the manufacturer’s datasheet for tda7294 typical application usage. Amplifier is ready to work with a powerful signal source, if necessary, use an opamp pre-amplifier. This type of 80w power amplifier circuit chip is ideal for surround sound systems. Since this is quite compact and can be used for independent amplifier for each speaker. In this way it can be upgraded to share source to support all of the connected amplifier.
