Description and Introduction

3W Audio Power Amplifier with Shutdown Mode The LM4871LD is a mono bridged audio power amplifier manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Power:** 1.1W into 8Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Quiescent Current:** 2.6mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **THD+N:** 0.2% (typical at 1kHz, 1W into 8Ω)  
- **PSRR:** 70dB (typical at 217Hz)  
- **Gain:** Fixed at 6dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
The LM4871LD is designed for battery-powered applications such as mobile phones, portable media players, and other low-voltage systems. It features a bridge-tied load (BTL) configuration, eliminating the need for an output coupling capacitor.  

### **Features:**  
- **Bridged Output (BTL):** No external coupling capacitor required  
- **Low Quiescent Current:** Extends battery life  
- **Low Shutdown Current:** Minimizes power consumption  
- **Unity-Gain Stable:** No external compensation needed  
- **Thermal Shutdown Protection:** Prevents damage from overheating  
- **Short-Circuit Protection:** Enhances reliability  
- **Improved PSRR:** Reduces power supply noise interference
