Overview


The LM386 audio amplifier is a high gain audio amplifier based on the LM386 integrated circuit. This low voltage audio power amplifier module is ideal if you need to add audio capabilities to your new project.


Features

  • 200x gain
  • Low distortion
  • On-board trimmer for volume control
  • Wide supply voltage range: from 5 V to 12 V
  • On-board power indicator
  • Board Size: 41 x 13 mm


Instructions for Use


1. Power up the audio amplifier.

The module is powered with a voltage between 5 V and 12 V. The supply pins are marked with VCC and GND. On the module are marked 2 pins with GND, but it does not matter which pin you connect the table.



2. Connect a speaker to the mode.


On the opposite side of the module, there are two screw terminals useful for connecting a speaker with a 8Ω impedance.


3. Connect an audio signal source.


The audio input is made through the pins marked with IN and GND.  If the audio signal and the power supply come from a common source (for example: an Arduino development board), you need to connect a single mesh wire (GND).


Example of use with an Arduino development board

The module connects to the development board:

  • a GND pin of the mode connects to a GND pin of the development board;
  • the  IN pin connects to the digital pin 8;
  • the VCC pin of the module connects to the 5V pin of the development board
