This is a simple design for power amplifier. This circuit is based on an IC that is LM1875. The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. The figure of the circuit is;
The feature of the power amplifier is producing 20 W Up to 30 W output power. AVO typically 90 dB. Low distortion: 0.015%, 1 kHz, 20 W. Wide power bandwidth: 70 kHz. It having protection for AC and DC short circuits to ground. Thermal protection with parole circuit. High current capability: 4A. Wide supply range 16V-60V. Internal output protection diodes. 94 dB ripple rejection.
