Description and Introduction

750mW Audio Power Amplifier with DC Volume Control and Headphone Switch The LM4865MX is a manufacturer by National Semiconductor (NS). Here are its specifications, descriptions, and features:

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

### **Descriptions:**  
The LM4865MX is a bridge-tied load (BTL) audio power amplifier designed for low-voltage applications. It is optimized for driving speakers in portable devices such as mobile phones, PDAs, and other battery-powered systems.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** 2.5mA (typical) for improved battery life.  
- **Shutdown Mode:** Reduces current consumption to 0.1µA (typical).  
- **Improved PSRR (Power Supply Rejection Ratio):** Minimizes noise from supply variations.  
- **Unity-Gain Stable:** No external gain-setting resistors required.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  

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