Description and Introduction

Boomer® Audio Power Amplifier Series 250mW Audio Power Amplifier with Shutdown Mode The LM4882MX is a dual audio power amplifier manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Output Power:**  
  - 1.1W per channel into 8Ω at 5V (THD+N = 1%)  
  - 325mW per channel into 8Ω at 3V (THD+N = 1%)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical) at 1kHz, 1W into 8Ω  
- **Shutdown Current:** 0.6µA (typical)  
- **Quiescent Current:** 4mA (typical)  
- **Gain Bandwidth Product:** 3MHz (typical)  
- **Slew Rate:** 2V/µs (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (M)  

### **Descriptions:**  
- The LM4882MX is a dual bridge-tied load (BTL) audio power amplifier designed for portable applications.  
- It features an internal depop circuit to reduce turn-on/off transients.  
- The device operates from a single supply and is optimized for low-voltage applications.  

### **Features:**  
- Dual BTL (Bridge-Tied Load) audio power amplifier  
- Low shutdown current (0.6µA typical)  
- No output coupling capacitors required  
- Improved PSRR (Power Supply Rejection Ratio) at 5V  
- Internal thermal shutdown protection  
- Space-saving SOIC-8 package  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.
