Description and Introduction

265mW at 3.3V Supply Audio Power Amplifier with Shutdown Mode 8-VSSOP -40 to 85 The LM4902MM/NOPB is a mono bridged audio power amplifier manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Type:** Mono Bridged Audio Power Amplifier  
- **Output Power:** 1W (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.2V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical)  
- **Quiescent Current:** 2.6mA (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **Gain:** Fixed at 6dB (2V/V)  
- **Package:** 8-Pin VSSOP (MM)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions and Features:**  
- Designed for low-voltage applications such as mobile phones, portable media players, and other battery-powered devices.  
- Features a bridge-tied load (BTL) configuration, eliminating the need for an output coupling capacitor.  
- Includes a low-power consumption shutdown mode.  
- Internal thermal shutdown protection.  
- Improved pop-and-click circuitry for reduced noise during power-up/power-down transitions.  
- Space-saving VSSOP package for compact PCB designs.  

This amplifier is optimized for driving small speakers efficiently in portable audio applications.
