Description and Introduction

Mono 1.5 W / Stereo 300 mW Power Amplifier The LM4850MMX is a manufacturer part from National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** LM4850MMX  
- **Type:** Audio Amplifier  
- **Package:** 10-VFSOP, 10-MSOP  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Output Power:**  
  - 1.1W (into 8Ω at 5V, THD+N = 10%)  
  - 350mW (into 8Ω at 3V, THD+N = 10%)  
- **Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.1μA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W into 8Ω)

- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM4850MMX is a mono, bridged audio power amplifier designed for portable electronic devices. It operates from a single power supply and delivers high-quality audio output with low distortion and noise. The device includes a shutdown mode to minimize power consumption when not in use.  

### **Features:**  
- Single-supply operation (2.7V to 5.5V)  
- Low quiescent current (4mA typical)  
- Ultra-low shutdown current (0.1μA typical)  
- No output coupling capacitors required  
- Thermal shutdown protection  
- Short-circuit protection  
- Space-saving MSOP package  

This information is strictly based on the manufacturer's datasheet and specifications.
