Lm386 Audio Amplifier Block Diagram. It is built by using popular amplifier lm386 ic. This circuit uses most simple and cost effective chip lm386 to build an audio amplifier.
Functional block diagram of lm386 functionally the lm386 audio amplifier ic can be divided in to amplifier gain control bypass power and output. Audio amplifiers are widely used in stereo or home theater systems mini speakers etc. Today we are going to make a simple audio amplifier circuit with lm386 ic.
Resistor r2 10k has been used as a pull up resistor to connect condenser mic to the positive supply voltage to provide the power to the mic.
There are numerous ways to build a audio amplifier circuit but nothing is efficient as building using a dedicated audio amplifier ic. Design of lm386 audio amplifier circuit. It s miles constructed via the use of the famous amplifier lm386 ic. You can also check the lm386 datasheet here.
