Description and Introduction

Mono 1.5 W / Stereo 300mW Power Amplifier 10-VSSOP -40 to 85 The LM4853MM/NOPB is a mono bridged audio power amplifier manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Power:** 3W into 4Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Shutdown Current:** 0.01μA (typical)  
- **Quiescent Current:** 3.5mA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.3% (typical at 1kHz, 1W into 4Ω)  
- **PSRR (Power Supply Rejection Ratio):** 70dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin MSOP (Micro Small Outline Package)  

### **Descriptions:**  
- The LM4853MM/NOPB is designed for mono audio applications in portable devices.  
- It features a bridge-tied load (BTL) configuration, eliminating the need for external coupling capacitors.  
- Includes a low-power shutdown mode for power-saving operation.  
- Provides thermal shutdown protection to prevent damage from excessive heat.  

### **Features:**  
- **Bridged Output:** Delivers higher power without requiring an output capacitor.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Shutdown Mode:** Reduces power consumption when inactive.  
- **Thermal Protection:** Prevents overheating.  
- **Improved PSRR:** Minimizes noise from power supply variations.  
- **Surface-Mount Package:** Suitable for compact PCB designs.
