This 80 Watt audio amplifier circuit uses IC TDA7295 as its main strength. The advantage of using an audio amplifier IC is a much simpler construction. IC TDA7295 is one that is popular with many features in it. Additionally IC TDA7295 has a very low distortion.
TDA7295 IC designed specifically for the class AB audio amplifier. Because of this amplifier circuit has a very low noise and distortion, it is very suitable for use in devices such as Hi-Fi audio home theater and high-class TV audio.
This amplifier circuit requires a power supply symmetric +/- 25 volts with 2A current. If will be assembled stereo, then the required current is 4 A. IC TDA7295 should be installed heatsink to prevent heat damage when the maximum working.
This audio amplifier circuit can be supplied above 25 Volt, but keep in mind the maximum voltage of not more than 40 Volt.
