Description and Introduction

Radio Control Receiver/Decoder The LM1872 is a monolithic power amplifier manufactured by National Semiconductor (NS). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:** 2W (typical) into 8Ω at 9V supply  
- **Supply Voltage Range:** 4V to 12V  
- **Quiescent Current:** 7mA (typical)  
- **Total Harmonic Distortion (THD):** 0.2% (typical) at 1kHz, 1W output  
- **Gain:** Internally fixed at 34dB (50x voltage gain)  
- **Bandwidth:** 20Hz to 20kHz  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The LM1872 is a low-power audio amplifier designed for consumer applications such as portable radios, intercoms, and small audio systems.  
- It is a Class AB amplifier with minimal external components required for operation.  
- The device includes internal thermal shutdown protection to prevent damage from overheating.  

### **Features:**  
- **Low Quiescent Current:** Ensures efficient power consumption.  
- **Thermal Shutdown Protection:** Safeguards the IC from overheating.  
- **Internally Fixed Gain:** Simplifies circuit design by eliminating the need for external gain-setting components.  
- **Wide Supply Voltage Range:** Operates from 4V to 12V, making it suitable for battery-powered applications.  
- **Minimal External Components:** Requires only a few capacitors and resistors for operation.  

This information is based on the manufacturer's datasheet for the LM1872 by National Semiconductor.
