Description and Introduction

LM381/LM381A Low Noise Dual Preamplifier The LM381AN is a low-noise dual preamplifier manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Supply Voltage Range:** ±5V to ±18V  
- **Input Noise Voltage:** 1.2μV (typical) at 1kHz  
- **Gain Bandwidth Product:** 15MHz  
- **Slew Rate:** 13V/μs  
- **Input Resistance:** 150kΩ  
- **Common Mode Rejection Ratio (CMRR):** 100dB (typical)  
- **Power Supply Rejection Ratio (PSRR):** 100dB (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 14-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The LM381AN is a dual-channel, high-performance preamplifier designed for low-noise audio applications.  
- It is optimized for use in tape playback amplifiers, microphone preamps, and other sensitive signal-conditioning circuits.  
- Each channel operates independently with matched characteristics for consistent performance.  

### **Features:**  
- **Low Noise:** Optimized for high-fidelity audio applications.  
- **Wide Supply Range:** Operates from ±5V to ±18V.  
- **High Gain Bandwidth:** Suitable for high-frequency applications.  
- **High CMRR & PSRR:** Ensures minimal interference from power supply variations and common-mode signals.  
- **Dual-Channel Design:** Two independent preamplifiers in a single package.  

This information is based on the manufacturer's datasheet for the LM381AN by National Semiconductor (NSC).
