Description and Introduction

675 mW Audio Power Amplifier with Shutdown Mode The LM4862MX is a manufacturer by National Semiconductor (NS). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Total Harmonic Distortion (THD):** 0.2% (typical at 1kHz, 1W output)  
- **Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.6μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM4862MX is a dual bridge-connected audio power amplifier designed for applications requiring low voltage operation and high-quality audio output. It is commonly used in portable devices such as mobile phones, PDAs, and portable media players.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates output coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Unity-Gain Stable:** No external compensation required.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from power supply variations.  
- **Space-Saving Package:** SOIC-8 for compact PCB designs.  

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