Description and Introduction

Integrated Audio Amplifier System The LM4852LQ is a manufacturer by National Semiconductor (NS). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel (into 8Ω at 5V)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
The LM4852LQ is a stereo audio power amplifier designed for portable applications. It features a low-voltage operation, making it suitable for battery-powered devices. The amplifier includes an integrated depop circuitry to minimize audible pops and clicks during power-up and shutdown.  

### **Features:**  
- Low quiescent current (3.6mA typical)  
- No external output coupling capacitors required  
- Thermal shutdown protection  
- Short-circuit protection  
- Improved click-and-pop suppression  
- Space-saving LLP package  

These details are based on the manufacturer's datasheet and specifications.
