    Bridged Audio Amplifier--TDA2030A

    Good day,all
    Today,I saw a article about introducing an audio amplifier built with TDA2030A in a bridged connection with a +-15v symmetric PS. As the following schematic diagram shows:

    The TDA2030A PDF
    In the article, it said that the audio power amplifier is easy to build,. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω speaker. Please use a good headsink to cool down the TDA2030A power amplifier.

    TDA2030A integrates circuits are very cheap and usefull if you want to start a small audio amplifier. The only thing you have to consider is to use a good power supply and heatsink or you’ll risk to burn this precious IC amplifier.

    The TDA2030A is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier.
    Typically it provides 14W output power (d = 0.5%) at 14V/4W; at ± 14V or 28V, the guaranteed output power is 12W on a 4W load and 8W on a 8W.
    I would like to ask that:
    1).I want to build this amplifier circuit using this diagram but before I do it I would like someone to ensure if it works properly.
    2)..What type of power supply is used in this circuit? Ac or Dc? What is +15v, -15v and gnd?

    Thank you.
    Best regards~
