Circuit Diagram
Working Explanation
The high-power headphone amplifier circuit is designed to deliver a high-quality audio experience to the listener. The low-pass filter R1/C2 regulates the input signal’s slew rate, preventing delay distortion and providing smooth audio playback.
To minimize crossover distortion, the output transistors are designed to draw a quiescent current of 30 mA, which is set by the diodes D1-D4 and emitter resistors R7 and R8. This amplifier delivers low distortion with a gain of 15 dB, set by feedback resistors R3 and R4. And bandwidth of -3 dB from 10 Hz to 30 kHz, coming in at just 0.1%.
With the ability to provide a maximum of 1 watt of power into an 8-ohm load for a 500 mVrms input signal, this circuit can easily drive 4-ohm loudspeakers and high-impedance headphones.
Conclusion
The High Power Headphone Amplifier Circuit offers a premium audio experience with its low-pass filter and fast LF 356, which reduces delay distortion.
