Description and Introduction

Stereo 2W Audio Power Amplifiers with DC Volume Control, Bass Boost, and Input Mux The LM4839MT is a manufacturer by National Semiconductor (NSC).  

**Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 1% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TSSOP  

**Descriptions:**  
The LM4839MT is a stereo audio power amplifier designed for low-voltage applications. It features a bridge-tied load (BTL) configuration, eliminating the need for external coupling capacitors.  

**Features:**  
- **Stereo Operation:** Supports two-channel audio output  
- **Low Voltage Operation:** Suitable for battery-powered devices  
- **No External Coupling Capacitors:** BTL configuration reduces component count  
- **Shutdown Mode:** Low power consumption when inactive  
- **Thermal Protection:** Prevents damage from overheating  
- **Pop & Click Suppression:** Minimizes noise during power-up/down  

This information is based on the manufacturer's datasheet.
