Description and Introduction

1 Watt Fully Differential Audio Power Amplifier With Shutdown Select The LM4898ITL is a manufacturer by National Semiconductor (NS). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **Quiescent Current:** 2.5mA (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical at 1kHz, 1W into 8Ω)  
- **PSRR (Power Supply Rejection Ratio):** 70dB (typical at 217Hz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 12-pin LLP (Leadless Leadframe Package)  

### **Description:**  
The LM4898ITL is a mono, bridged audio power amplifier designed for portable applications. It operates from a single supply voltage and delivers high-quality audio output with low power consumption. The device includes an internal shutdown feature to minimize power draw when not in use.  

### **Features:**  
- **Bridged Output:** Eliminates the need for external coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Improved PSRR:** Reduces noise from power supply variations.  
- **Small Footprint:** 12-pin LLP package saves board space.  
- **No External Bootstrap Capacitors Required:** Simplifies design.  

This information is strictly factual from the available knowledge base.
