Circuit Diagram
Working Explanation
The Simple 100 Watt Amplifier Circuit using a Single IC is a compact and efficient amplifier circuit that utilizes an LM12CLK integrated circuit for processing. The IC has a powerful output stage capable of operating at low impedances, as low as 2 ohms, and delivering up to 150W of power. However, for safety and stability, the circuit is designed to work with 4-ohm speakers, resulting in an RMS power of 100W.
The power supply transformer must provide 24v + 24v of AC supply in its secondary with a minimum of 5A current for mono or 10A for stereo. A metal rectifier bridge unit is recommended instead of using four diodes for the bridge rectifier unit and should be fitted with a heat sink.
The output coil, L, is created by winding 14 turns of No. 18 wire with a 1-inch diameter and no core. The coil’s turn distance is not critical to performance.
The circuit uses a precision resistor with a value of 1.1K. The output resistance must be rated for at least 2W power. The electrolytic capacitors in the circuit must be rated at 50V or 63V. With these components, a circuit can give a robust and high-quality audio experience.
Final Words
With this project, you will be able to bring your audio setup to the next level. Not only is the circuit compact and efficient, but it also can deliver powerful, high-quality sound. Assemble it with ease and enjoy the stunning audio output. So why not take the next step and build your own 100 Watt Amplifier Circuit using a Single IC today?
