Description and Introduction

Ultra-Low EMI, Filterless, 2.5W, Stereo, Class D Audio Power Amplifier with E 2 S 16-DSBGA -40 to 85 The LM48411TL/NOPB is a mono Class D audio power amplifier manufactured by National Semiconductor (now part of Texas Instruments). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Power:** 1.1W (into 8Ω at 5V, THD+N = 10%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90% (Class D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** <1% (typical)  
- **Shutdown Current:** <1μA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 9-bump DSBGA (Micro SMD)  

### **Descriptions:**
- A high-efficiency, mono Class D audio amplifier designed for portable applications.  
- Features a low-power shutdown mode for battery-powered devices.  
- Includes click-and-pop suppression for smooth power-up/down transitions.  

### **Features:**
- **Low Quiescent Current:** 2.5mA (typical)  
- **Filterless Operation:** Eliminates the need for external LC filters.  
- **Short-Circuit Protection:** Includes thermal and overcurrent protection.  
- **Small Footprint:** Ideal for space-constrained designs.  
- **Single-Supply Operation:** Simplifies power management.  

This information is based on the manufacturer's datasheet. For detailed performance curves and application circuits, refer to the official documentation.
