According to wikipedia.org, an Audio Amplifier is a an electronic amplifier that amplifies low-power audio signals (20 – 20 000 Hz) to a level suitable for driving loudspeakers. Key design parameters for audio amplifiers are frequency response, gain, noise, and distortion. Below schematic shows the design of a Simple Audio Amplifier Circuit Diagram using LM386. The LM386 is a 8 pin MSOP package power amplifier designed for use in low voltage application. (click image to enlarge)
