TDA2009 single power amplifier circuit diagram

I have always wanted to do a morning exercise machine, but I have been unable to find a high-power single- power amplifier . Because the morning exercise machine is battery-powered, I have been thinking about it for several months. Finally, I found a TDA2009 single- power amplifier IC. Now I am working with it. Please share the application circuit diagram of TDA2009.

TDA2009 is a common and affordable high-fidelity power amplifier integrated block. Rated power is 2×10W. The power supply voltage is 8~28V. The maximum output current is 3.5A. Has overheating protection circuit. (2×10W, THD=0.5%)

According to the author's several sets of power amplifiers built using this chip, the effect is still very good. It has been used to this day for several years without any failures. Of course, as introduced in the "Ground Wire Design Tips" chapter, the premise is that the ground wire design must be reasonable. In addition, although it generates very little heat, you still need to pay attention to heat dissipation. The circuit diagram is as follows:
