Description and Introduction

Dual Operational Amplifier The LM747 is a dual general-purpose operational amplifier manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** ±5V to ±18V  
- **Input Offset Voltage:** 2 mV (typical)  
- **Input Bias Current:** 80 nA (typical)  
- **Input Offset Current:** 20 nA (typical)  
- **Common-Mode Rejection Ratio (CMRR):** 90 dB (typical)  
- **Power Supply Rejection Ratio (PSRR):** 96 dB (typical)  
- **Slew Rate:** 0.5 V/µs (typical)  
- **Gain Bandwidth Product:** 1 MHz (typical)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The LM747 is a dual version of the LM741 op-amp, featuring two independent amplifiers in a single package.  
- It is designed for general-purpose applications, including amplifiers, comparators, and signal conditioning circuits.  
- The device offers high gain, wide bandwidth, and stable operation under varying conditions.  

### **Features:**  
- **Dual Operational Amplifier:** Two op-amps in one package.  
- **Short-Circuit Protection:** Built-in protection against output short circuits.  
- **No Latch-Up:** Designed to prevent latch-up under high input voltage conditions.  
- **Wide Supply Voltage Range:** Supports both single and dual power supplies.  
- **Internal Frequency Compensation:** Eliminates the need for external compensation components.  

The LM747 is commonly used in audio amplifiers, active filters, and instrumentation circuits.
