TDA1514 Audio Amplifier Circuit

Here’s a circuit for TDA1514 audio amplifier circuit that is capable to provide a high audio power output using a specialized audio IC and other few common components. The TDA1514 audio IC is 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 loads and require few external components. This is the figure of the amplifier circuit diagram;


This 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 inter modulation 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.
