Description and Introduction

300 mW Audio Power Amplifier with Shutdown Mode The LM4864M is a manufacturer by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel into 8Ω at 5V (typical)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Quiescent Current:** 4mA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W output)  
- **Shutdown Current:** 0.1μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM4864M is a dual bridge-connected audio power amplifier designed for applications requiring low voltage operation and high-quality audio output. It is suitable for portable devices such as smartphones, tablets, and portable media players.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Low Shutdown Current:** Reduces power consumption when inactive.  
- **Improved PSRR (Power Supply Rejection Ratio):** Minimizes noise from the power supply.  
- **Surface-Mount Package (SOIC-8):** Compact footprint for space-constrained designs.  

This information is based solely on the manufacturer's datasheet for the LM4864M.
