LM386 IC | LM386N-1 Audio Amplifier IC (BWQ51 Variant) | Low Voltage Mono Audio Power Amplifier IC for DIY Electronics, Arduino & Speaker Projects

The LM386 is a low-power audio amplifier IC designed for use in small audio systems, DIY speakers, Arduino sound projects, and portable devices. It is widely used because it works on low voltage and requires very few external components.

Specifications

• Supply voltage: 4 V to 12 V (for the N-1 version)
• Voltage gain: 20 by default (26 dB)
• Maximum gain: 200 (46 dB) by adding a capacitor between pins 1 and 8
• Output power: Around 0.3–0.7 W depending on supply voltage and speaker impedance
