Description and Introduction

1.1W Audio Power Amplifier with Logic Low Shutdown The LM4876M is a power amplifier manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** 3W (into a 3Ω load at 5V)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical at 1W into 8Ω)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (M)  

### **Descriptions:**  
- The LM4876M is a mono bridged audio power amplifier designed for low-voltage applications.  
- It features a differential input architecture to reduce noise and improve performance.  
- The device includes thermal shutdown and short-circuit protection.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Shutdown Mode:** Reduces power consumption when not in use.  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Surface-Mount Package:** Suitable for compact PCB designs.
