Fig. 12.1. 12.1 Transistor Audio Power Amplifier. A transistor amplifier which raises the power level of the signals that have audio frequency range is known as tran-sistor audio power amplifier. . The power amplifier differs from all the previous stages in that here a concentrated effort is made to obtain maximum output pow.
LM386 Low Voltage Audio Power Amplifier 1 Features • Battery Operation • Minimum External Parts • Wide Supply Voltage Range: 4 V–12 V or 5 V–18 V • Low Quiescent Current Drain: 4 mA • Voltage Gains from 20 to 200 • Ground-Referenced Input • Self-Centering Output Quiescent Voltage • Low Distortion: 0.2% (AV = 20, VS = 6 V, RL ...
power amplifier can be regarded as complete until it has proper DC protection – having an amplifier fail is bad enough, but having it fail and take an expensive loudspeaker with it is downright upsetting.

This book is the essential reference for audio power amplifier designers and engineers. Author Douglas Self covers all the issues of distortion and linearity, power supplies, protection, reliability and layout.
power amplifier design and distortion measurement in the popular press and in the Journal of the Audio Engineering Society. In 1983 he published a power amplifier design combining vertical power MOSFETs with error correction, achieving unprecedented distortion levels of less than 0.001% at 20 kHz.
