Connect Pin 5 (Output) to the positive terminal of the 250µF capacitor, and the negative terminal to your speaker.
This is the quintessential first audio amplifier project. Its low component count, straightforward construction, and ability to be powered by a 9V battery make it ideal for beginners.
For temporary prototyping and testing circuits before permanent assembly.
Electrolytic capacitors for power filtering; ceramic or polyester film capacitors for the audio signal path.
This circuit requires a split power supply (+12V, 0V, -12V). Bridge the positive and negative rails with 2200µF reservoir capacitors right next to the IC pins to eliminate 50/60 Hz hum.
The LM386 is an iconic integrated circuit (IC) that requires minimal external components.
