Description and Introduction

LM4808 Dual 105 mW Headphone Amplifier The LM4808M is a dual audio power amplifier manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Output Power:**  
  - 105mW per channel into 32Ω at 5V  
  - 80mW per channel into 16Ω at 3.3V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical) at 1kHz, 32Ω load  
- **Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **Gain:** Fixed at 6dB (2V/V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (LM4808M)  

### **Descriptions:**  
- The LM4808M is a dual audio power amplifier designed for portable electronic devices.  
- It operates from a single supply voltage, making it suitable for battery-powered applications.  
- The amplifier features an internal depop circuitry to reduce turn-on/off transients.  
- It includes thermal shutdown protection to prevent damage from excessive heat.  

### **Features:**  
- Dual-channel audio amplifier  
- Low quiescent current for extended battery life  
- No external coupling capacitors required  
- Improved click-and-pop suppression  
- Thermal shutdown protection  
- Space-saving 8-pin SOIC package  

This information is based solely on the manufacturer's datasheet for the LM4808M.
