The LM386 is an iconic integrated circuit (IC) that requires minimal external components.

These chips operate similarly to high-power operational amplifiers (Op-Amps). They require heavy negative feedback to keep the audio signal clean. A resistor divider network connects from the output pin back to the inverting input pin to set the exact gain level. Thermal Management Warning practical audio amplifier circuit projectspdf
