Description and Introduction

Stereo 2W Audio Power Amplifiers with DC Volume Control and Selectable Gain The LM4835 is a stereo audio power amplifier manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Output Power:**  
  - 1.1W per channel into 8Ω at 5V (THD+N = 10%)  
  - 700mW per channel into 8Ω at 3.3V (THD+N = 10%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Operating Current:** 4mA (typical)  
- **Gain:** Fixed at 6dB  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Package:** 16-pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
The LM4835 is a low-voltage, low-power stereo audio amplifier designed for portable applications. It features a shutdown mode for power savings and operates efficiently from a single supply.  

### **Features:**  
- **Stereo Audio Amplifier**  
- **Low Quiescent Current**  
- **Low Shutdown Current**  
- **Thermal and Short-Circuit Protection**  
- **No External Output Coupling Capacitors Required**  
- **Space-Saving LLP Package**
