Intercom Circuit Using LM IC | Circuit Diagram

This audio amplifier module can be used to play your FM receiver kit, make infrared based music transmitter and receiveretc. A low cost LM based Audio Amplifier is available on www. You can use the amplifier module for your project. In this video, I have plugged in a simple FM receiver kit.


The audio amplifier amplifies the sound of FM receiver. I have tested it on Proteus. ITS working fine, but the Kind of waves it producing as output as not sinusoidal wave.

The wave is like something else. Can I use this design as stereo amplifier; I mean dual channel amplifier. And another question is if there untercom an amplifier whose gain starts from 1 and is adjustable, please tell me its name.

Hello May I ask a question? I would like it to be powered by a 9v battery….
