LM386 Audio Amplifier Module

Description

The LM386 Audio Amplifier Module is a compact and efficient device designed to amplify audio signals with ease. With its simple interface and powerful capabilities, it is an excellent choice for various audio amplification applications. The module is built around the LM386 amplifier chip, which provides high-quality audio amplification. It can amplify low-power audio signals and deliver them with increased volume and clarity.

Operating the LM386 module is straightforward. It features a few external components for adjusting the gain and controlling the audio input and output. This allows for easy customization and fine-tuning of the amplification process. The amplifier integrated circuits are LM386M-1. They operate between 4V and 12V and have a power output of up to 325mW. The output can power loads ranging from 4 to 32 ohms. The lower the load resistance, the more power it can provide, so a 4-ohm speaker will be roughly twice as loud as an 8-ohm speaker.

The gain is fixed at 200x, but the volume can be adjusted using the module’s potentiometer, which controls the signal level fed to the LM386 IC. The module supports a wide range of input voltage and has built-in protection against electrical overloads, ensuring safe and reliable operation. It also features a speaker output for connecting external speakers or headphones.
