How to make a Voice intercom using the LM386
The next project that I have uploaded is the LM386 Single Phase Audio Amplifier. This IC is well known for audio applications, operates at very low voltage, is very inexpensive, and is capable of producing audio power up to 1W.
In today's video, I talk about the LM386 datasheet, listing its electrical characteristics, its functionalities, what it is used for... etc. Then with the Proteus simulator I perform a more detailed analysis of the audio amplifier circuit and finally the implementation of the circuit on the breadboard.
How to make an audio amplifier with LM386 easy and with tricks you didn't know to improve it. Tricked and improved amp. Amplifier for cell phone or smartphone easy, economical and cheap. improved circuit. Experiments and electronic classesasamide
Integrated LM386 : the LM386N-4 is the one that gives the most power (1W) and the LM386N-1 the one that gives the least (0.325W)
9V battery
10k potentiometer (by turning the axis of the potentiometer you can regulate the volume)
220 microfarad electrolytic capacitor at 16V or higher
1W or higher 4 or 8 ohm speaker
0.05 microfarad or 0.1 microfarad ceramic capacitor
10 ohm resistor
10 microfarad electrolytic capacitor at 16V minimum
pieces of cables
perforated plate
