Description and Introduction

1.1 Watt Audio Power Amplifier The LM4893ITL is a manufacturer by National Semiconductor (NS). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical)  
- **Shutdown Current:** <1μA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
- The LM4893ITL is a mono, bridged audio power amplifier designed for portable applications.  
- It features a low-power consumption shutdown mode and requires minimal external components.  
- Suitable for driving small speakers in mobile phones, PDAs, and other battery-powered devices.  

### **Features:**  
- **Bridged Output:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** 2.7mA (typical) for extended battery life.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from power supply variations.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Space-Saving Package:** 10-pin LLP for compact PCB designs.  

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