Schematics Simple Audio Amplifier Circuit Using LM386 PCB

Circuit
Here is a simple low power audio amplifier circuit that can produce a power output of 1W. This mono amplifier circuit is build on LM386 IC which works great on low voltages even below 9V. This low voltage amplifier is useful to amplify weak sound signals from your soundcard to amplify it to give to the headphones  or high power amplifiers for maximum sound effect.
