Description and Introduction

2.2W Stereo Audio Amplifier 20-HTSSOP -40 to 85 The LM4866MTEX/NOPB is a dual bridge-connected audio power amplifier manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Audio Power Amplifier  
- **Configuration:** Dual Bridge (BTL)  
- **Output Power:** 2.5W per channel (into 4Ω at 5V)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Quiescent Current:** 4mA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W into 4Ω)  
- **Shutdown Current:** 0.1μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-28  

### **Descriptions:**  
The LM4866MTEX/NOPB is a dual bridge-tied load (BTL) audio amplifier designed for portable applications such as mobile phones, PDAs, and portable media players. It operates from a single supply voltage and provides high-quality audio output with low distortion and noise.  

### **Features:**  
- **Dual BTL Outputs:** Eliminates the need for external coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier and connected components.  
- **Space-Saving TSSOP-28 Package:** Suitable for compact designs.  
- **No External Bootstrap Capacitors Required:** Simplifies circuit design.  
- **Unity-Gain Stable:** Works without external compensation.  

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