This audio amplifier circuit is capable to provide a high audio power using a specialized audio IC and other few common components . The heart of this audio amplifier circuit is the TDA1514 audio IC manufactured by Philips Semiconductor and is capable to provide an output audio power up to 50 W . TDA1514 50W audio amplifier supports 4 or 8 ohms lads and require few external components .

The TDA1514 50W audio amplifier support a wide input voltage range from 10 volts up to 30 volts and it has many other build in features like :   low harmonic distortion , low intermodulation distortion , low offset voltage , good ripple rejection , mute/stand-by facilities , thermal protection , protected against electrostatic discharge , very low thermal resistance ,  Safe Operating Area (SOAR) protection.
This audio IC can be used for audio stages of TV , radios or other devices . The device is intended for symmetrical power supplies but an asymmetrical supply may also be used.
