Description and Introduction

Ceramic Speaker Driver The LM4961LQ is a high-performance audio amplifier manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V supply)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Shutdown Current:** <1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
- The LM4961LQ is a mono, filterless Class D audio amplifier designed for portable applications.  
- It features a high-efficiency switching architecture, minimizing power consumption while delivering high-quality audio output.  
- The device includes an integrated boost converter to enhance output power when operating from low-voltage supplies.  

### **Features:**  
- **Filterless Class D Operation:** Eliminates the need for external LC filters.  
- **Integrated Boost Converter:** Enhances output power in low-voltage applications.  
- **Low Quiescent Current:** Optimized for battery-powered devices.  
- **Thermal and Short-Circuit Protection:** Ensures safe operation under fault conditions.  
- **Pop-and-Click Suppression:** Reduces audible noise during power-up and shutdown.  
- **Small Footprint:** 16-pin LLP package saves board space.
