Description and Introduction

1.1 Watt Audio Power Amplifier The LM4879ITL is a manufacturer by National Semiconductor (NS). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 3W (into 3Ω at 5V)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical at 1W into 3Ω)  
- **Shutdown Current:** 0.01μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
The LM4879ITL is a mono, bridge-tied load (BTL) audio amplifier designed for portable applications. It delivers high-quality audio output with low power consumption, making it suitable for battery-powered devices like smartphones, tablets, and portable media players.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** 4mA (typical) for improved battery life.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  
- **Space-Saving Package:** 8-pin LLP for compact PCB designs.  

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