Description and Introduction

2 Watt Audio Power Amplifier with Selectable Shutdown Logic Level The LM4990MMX is a power amplifier manufactured by National Semiconductor (NS). Here are its 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):** 0.2% (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin VSSOP (MMX)  

### **Descriptions:**  
- The LM4990MMX is a mono, bridged audio power amplifier designed for portable applications.  
- It operates from a single supply and is optimized for low-voltage, battery-powered systems.  
- Includes a shutdown feature to minimize power consumption when not in use.  

### **Features:**  
- **Low Quiescent Current:** 2.6mA (typical)  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces power supply noise.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Bridged Output:** Eliminates the need for external coupling capacitors.  
- **Surface-Mount Package:** Compact 8-pin VSSOP for space-constrained designs.  

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