Description and Introduction

1 Watt Audio Power Amplifier with Headphone Sense The LM4892IBP is a power amplifier manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W (into 8Ω at 5V, THD+N = 10%)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **Shutdown Current:** 0.01μA (typical)  
- **Quiescent Current:** 2.5mA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W into 8Ω)  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM4892IBP 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 other battery-powered systems. The amplifier features a shutdown mode to minimize power consumption when not in use.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Shutdown Mode:** Reduces power consumption when inactive.  
- **Improved PSRR (Power Supply Rejection Ratio):** Minimizes noise from the power supply.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier from output faults.  

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