I built almost a dozen different audio amplifier circuits with. If you are beginner then this post for you. The simple schematic diagram of two transistor audio amplifier is shown in the below. Schematic simple audio amplifier. Its function is not voltage gain but current or power gain and impedance matching. 7V from base to emitter of the transistor. 40W to 55W transistors audio amplifier This circuit is one that stands out for ages over 40 years, with sound quality that is hard to find compared be other circuits. RC coupled amplifier Capacitor Cin is the input DC decoupling capacitor which blocks any DC component if present in the input signal from reaching the Q1 base. Audio Amplifier Circuit Overview In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based on the LM386 IC from National Semiconductor. It is designed to load the amplifier for optimum power output with a minimum of harmonic content. Our next transistor configuration to study is a bit simpler for gain calculations.
