Description and Introduction

Quad Operational Amplifier (JFET) The LF347N is a quad JFET-input operational amplifier (op-amp) manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Number of Channels:** 4 (Quad)
- **Supply Voltage Range:** ±18V (Dual Supply), 36V (Single Supply)
- **Input Offset Voltage:** 5 mV (max)
- **Input Bias Current:** 50 pA (typ)
- **Slew Rate:** 13 V/µs (typ)
- **Gain Bandwidth Product:** 4 MHz (typ)
- **Input Common-Mode Voltage Range:** V- to V+ - 3V
- **Output Voltage Swing:** ±13.5V (with ±15V supply)
- **Operating Temperature Range:** 0°C to +70°C
- **Package:** 14-Pin PDIP (Plastic Dual In-Line Package)

### **Descriptions:**
- The LF347N is a high-speed JFET-input operational amplifier with low input bias current and offset voltage.
- It is designed for applications requiring wide bandwidth, high slew rate, and low noise.
- The JFET input stage provides high input impedance and low input current.
- Suitable for audio, instrumentation, and signal conditioning applications.

### **Features:**
- **Low Input Bias Current:** 50 pA (typ)
- **High Input Impedance:** 10¹² Ω (typ)
- **Low Noise:** 25 nV/√Hz (typ)
- **Wide Bandwidth:** 4 MHz (typ)
- **High Slew Rate:** 13 V/µs (typ)
- **Internally Trimmed Offset Voltage**
- **No Latch-Up**
- **Low Power Consumption**

This information is based on the manufacturer's datasheet for the LF347N.
