This audio amplifier circuit amplifier is based on the TDA7056 integrated audio amplifier circuit . This TDA7056 audio amplifier will provide a maximum output power of 1 watt into a 8 ohms load using a 6 volts power supply , or a maximum output power of 3 watts into a 16 ohms load using a 11 volts power supply .
Because of the low numbers of components required ,the TDA7056 audio amplifier circuit can be used for portable equipments .
The gain of the audio IC is internally fixed at 40 dB. The maximum input voltage supported by this circuit is 18 volts .
As you can see in the circuit diagram you will need just two capacitors and one resistor to construct this audio amplifier . The TDA IC don’t need to be mounted on a heatsink.
