The LM386 Low Voltage Audio Amplifier IC is a compact and efficient power amplifier tailored for low-voltage consumer electronics. It offers a built-in gain of 20 to minimize the need for external components but allows gain customization from 20 to 200 with a simple resistor-capacitor combination. With its ground-referenced inputs and output biased to half the supply voltage, the LM386 is an excellent solution for battery-powered and space-constrained designs.
Thanks to its low quiescent power drain of just 24 mW when operating at 6V, it is ideal for portable audio devices, small speaker systems, intercoms, and DIY electronics projects. The LM386 requires minimal external circuitry and comes in a DIP-8 package for easy breadboarding and prototyping.
