Description and Introduction

LM4908 10kV ESD Rated, Dual 120mW Headphone Amplifier The LM4908MA is a manufacturer by National Semiconductor (NS). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical at 1kHz, 1W into 8Ω)  
- **Quiescent Current:** 2.7mA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM4908MA is a mono, bridged audio power amplifier designed for portable applications. It operates from a single supply and delivers high-quality audio output with low power consumption. It includes an internal thermal shutdown protection feature and requires minimal external components.

### **Features:**  
- **Bridged Output:** Eliminates the need for an output coupling capacitor.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **No Output Coupling Capacitors Needed:** Reduces component count.  
- **Space-Saving SOIC-8 Package:** Suitable for compact designs.  

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