Description and Introduction

Fixed Gain 1 Watt Audio Power Amplifier The LM4820M-6 is a mono bridged audio power amplifier manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** 1.1W (typical) into an 8Ω load at 5V supply.  
- **Supply Voltage Range:** 2.7V to 5.5V.  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical) at 1W into 8Ω.  
- **Quiescent Current:** 4mA (typical).  
- **Shutdown Current:** 0.6μA (typical).  
- **Gain:** Fixed at 6dB.  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** 8-pin SOIC.  

### **Descriptions:**  
- The LM4820M-6 is designed for battery-powered applications requiring high efficiency and low power consumption.  
- It features a bridge-tied load (BTL) configuration, eliminating the need for an output coupling capacitor.  
- Includes a low-power shutdown mode for power-saving operation.  

### **Features:**  
- **Bridged Output:** No external coupling capacitors required.  
- **Low Quiescent Current:** Ideal for portable devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  
- **Space-Saving Package:** 8-pin SOIC for compact designs.  

This information is based on the manufacturer's datasheet. For detailed performance characteristics, refer to the official documentation.
