Description and Introduction

Low voltage audio power amplifier. Supply voltage range: 4V-12V. The LM386 is a low-voltage audio power amplifier manufactured by QT.  

**Specifications:**  
- **Supply Voltage Range:** 4V to 12V (or 5V to 18V in some versions)  
- **Output Power:** Up to 1W (depending on supply voltage and load impedance)  
- **Gain Range:** Adjustable from 20x to 200x via external components  
- **Quiescent Current:** ~4mA  
- **Total Harmonic Distortion (THD):** ~0.2% (typical)  
- **Bandwidth:** ~300kHz  
- **Input Impedance:** ~50kΩ  

**Descriptions:**  
The LM386 is a mono amplifier designed for low-power audio applications. It is commonly used in battery-operated devices due to its low power consumption. The IC features an internal gain setting (default 20x) that can be increased up to 200x with external resistors and capacitors.  

**Features:**  
- Low quiescent power drain  
- Operates from a single power supply  
- Minimal external components required  
- Internal frequency compensation  
- Input referenced to ground  
- Available in 8-pin DIP and SOIC packages
