Description and Introduction

Quad Operational Amplifier (JFET) The LF347M is a quad JFET-input operational amplifier manufactured by NS (National Semiconductor).  

### **Specifications:**  
- **Number of Channels:** 4  
- **Supply Voltage Range:** ±18V (max)  
- **Input Offset Voltage:** 5 mV (max)  
- **Input Bias Current:** 50 pA (typ)  
- **Input Offset Current:** 25 pA (typ)  
- **Gain Bandwidth Product:** 4 MHz (typ)  
- **Slew Rate:** 13 V/µs (typ)  
- **Common Mode Rejection Ratio (CMRR):** 100 dB (typ)  
- **Power Supply Rejection Ratio (PSRR):** 100 dB (typ)  
- **Operating Temperature Range:** -25°C to +85°C  

### **Descriptions and Features:**  
- **JFET-Input:** Provides high input impedance and low input bias current.  
- **Low Noise:** Suitable for precision analog applications.  
- **Wide Bandwidth:** 4 MHz typical gain bandwidth product.  
- **High Slew Rate:** 13 V/µs for fast signal response.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Internal Frequency Compensation:** Ensures stability without external components.  
- **High CMRR and PSRR:** Improves noise rejection in noisy environments.  

The LF347M is commonly used in audio amplifiers, active filters, and instrumentation circuits due to its high input impedance and low noise characteristics.
