Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

What is the LM386 audio amplifier? The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package.

前に製作したアナログVUメーターに中華製のLM386アンプを追加して再構成しました。 今回、LM386アンプを取り付けたのは100円ショップの今は販売中止の小型スピーカーを動かしてみよう、と考えての再構築になりました。 アナログVUメーターはアルミ板を自分 ...

This repository contains the KiCad project files for a simple audio amplifier based on the LM386 IC. This amplifier is designed for low-power audio applications and is suitable for use with small ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

If you already know about class A, B, and AB, they are all linear amplifiers with constant gain where the audio is fed to the base of a transistor. The latest class D audio amplifier is switch type ...
