Description and Introduction

2.2W Stereo Audio Amplifier The LM4866MTX is a manufacturer by National Semiconductor (NS). Here are the factual details about the part:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel into 8Ω (at 5V, THD+N = 10%)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Operating Current:** 4mA (typical)  
- **Shutdown Current:** 0.6μA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W output)  
- **Gain:** Fixed at 6dB  
- **Package:** 8-Pin SOIC (TSSOP)  

### **Descriptions:**  
- The LM4866MTX is a dual bridge-connected audio power amplifier designed for portable applications.  
- It features a low-power consumption shutdown mode and requires minimal external components.  
- It is optimized for driving speakers in battery-powered devices such as mobile phones and PDAs.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** Extends battery life.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  
- **Space-Saving Package:** 8-pin SOIC (TSSOP) for compact designs.
