Description and Introduction

1 Watt Audio Power Amplifier with Headphone Sense The LM4892M is a manufacturer by National Semiconductor (NS). Here are the factual details from Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Shutdown Current:** <1µA  
- **Quiescent Current:** 2.6mA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.3% (typical at 1kHz, 1W into 8Ω)  
- **PSRR (Power Supply Rejection Ratio):** 70dB (typical at 217Hz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The LM4892M is a mono, bridged audio power amplifier designed for low-voltage applications. It is optimized for driving speakers in portable devices such as mobile phones, PDAs, and portable media players. The amplifier features an integrated shutdown mode to minimize power consumption when inactive.

### **Features:**  
- **Bridged Output:** Eliminates the need for an external coupling capacitor.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR:** Reduces noise from power supply variations.  
- **Small Footprint:** Suitable for space-constrained designs.  

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