32 watt audio amplifier circuit using TDA2050

This 32 watt audio amplifier circuit using TDA2050 is designed using the TDA2050 integrated circuit a very simple high fidelity audio power amplifier, intended for use as an audio class AB audio amplifier.
The 32 watt audio amplifier circuit based on TDA2050 can be used both HiFi and high class TV sets.
Thanks to its high power capability the TDA2050 integrated circuit audio power amplifier is able to provide up to 35W true rms power into 4 ohm load @ THD = 10%, VS =18V, f = 1KHz and up to 32W into 8ohm load @ THD = 10%, VS = 22V, f = 1KHz.
The audio IC must be mounted on a heat sink with no electrical isolation between IC package and heat sink . For a better thermal contact between heat sink and the audio IC package we must apply a layer of silicon grease between this two surfaces.
