Output-Transient-Free Dual 2.1W Audio Amplifier Plus No Coupling Capacitor Stereo Headphone Function The LM4868MTX is a manufacturer part from National Semiconductor (NS). Here are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Description:**  
The LM4868MTX is a dual bridge-connected audio power amplifier designed for applications requiring high-quality audio output, such as portable devices, desktop computers, and multimedia systems.  

### **Key Features:**  
- **Output Power:**  
  - 1.1W per channel into 8Ω at 5V (THD+N = 10%)  
  - 700mW per channel into 16Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Low Quiescent Current:** 4mA (typical)  
- **Shutdown Current:** 0.6μA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical at 1kHz, 1W output)  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors  
- **Thermal Shutdown Protection:** Prevents damage from overheating  
- **Surface-Mount Package:** 28-pin TSSOP (MTX)  

### **Applications:**
