LM386MX-1/NOPB Audio Amplifier IC | TI Low-Voltage SOIC-8 Amp

The LM386MX-1/NOPB from Texas Instruments is a widely used low-voltage audio power amplifier designed for compact and battery-powered audio applications. Packaged in an SOIC-8 surface-mount package, this amplifier delivers up to 700 mW output power (at 9V, 8Ω load) while requiring minimal external components—making it ideal for portable audio, intercoms, small speaker drivers, hobby electronics, and DIY amplifier circuits.

The LM386 features an internally set gain of 20, easily boostable to 200 using external components, allowing flexible audio amplification performance. With its low harmonic distortion, thermal overload protection, and low quiescent current, it ensures clean, efficient, and reliable audio output.
