The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply . The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.
soo today i am going to show you how to make a low frequency audio amplifier using the LM386 .
Step 1: Getting Started
Have fun building your amp.. :)
