Description and Introduction

Dual 200 mW Audio Power Amplifier with Shutdown Mode The LM4880M is an audio power amplifier manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on the provided knowledge base:

### **Specifications:**
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Output Power:** 1.1W (typical) into an 8Ω load at 5V  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical) at 1kHz, 1W output  
- **Shutdown Current:** 0.6µA (typical)  
- **Quiescent Current:** 3mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (M)  

### **Descriptions:**
The LM4880M is a low-voltage, high-performance audio power amplifier designed for portable electronic devices. It is optimized for driving speakers with minimal external components and low power consumption. The device features a shutdown mode to further reduce power usage when not in operation.

### **Features:**
- Low voltage operation (2.7V to 5.5V)  
- High output power (1.1W at 5V into 8Ω)  
- Low THD+N for high-quality audio  
- Ultra-low shutdown current (0.6µA)  
- No output coupling capacitors required  
- Internal thermal shutdown protection  
- Space-saving 8-pin SOIC package  

The LM4880M is suitable for battery-powered applications such as mobile phones, portable media players, and handheld gaming devices.
