LM386 - Low Voltage Power Amplifier - DIP IC

LM386 Low Voltage Power Amplifier - DIP IC for Audio Projects

The LM386 is a highly efficient low-voltage power amplifier, ideal for consumer electronics and battery-powered applications. This versatile DIP IC features an internally preset gain of 20, minimizing the need for external components. For greater flexibility, its gain can be adjusted up to 200 by adding a simple resistor and capacitor. Operating efficiently at just 24 milliwatts on a 6-volt supply, it's optimized for portable systems. With ground-referenced inputs and an output automatically biased at half the supply voltage, the LM386 ensures stable and consistent performance. Its low quiescent current of 4 mA further enhances energy efficiency, making it a top choice for compact audio amplification.
