Description and Introduction

2W Monaural, 90mW Stereo Headphone Audio Amplifier The LM4913MH is a mono bridged audio power amplifier manufactured by Texas Instruments. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** 1.1W into 8Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **Quiescent Current:** 2.2mA (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W into 8Ω)  
- **Gain:** Fixed at 6dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MH)  

### **Descriptions:**  
- The LM4913MH is designed for mono audio applications in portable devices.  
- It features a bridge-tied-load (BTL) configuration, eliminating the need for an output coupling capacitor.  
- Includes a low-power consumption shutdown mode.  

### **Features:**  
- **Bridged Output:** Delivers higher power without requiring large supply voltages.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from the power supply.  
- **No Output Coupling Capacitor Needed:** Simplifies design and reduces component count.  

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