Description and Introduction

Dual Low Power JFET Input Operational Amplifier The LF442ACN is a dual JFET-input operational amplifier manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
Texas Instruments  

### **Description:**  
The LF442ACN is a low-power, dual operational amplifier with JFET inputs. It is designed for applications requiring high input impedance, low input bias current, and low power consumption.  

### **Key Features:**  
- **JFET-Input:** Provides high input impedance and low input bias current.  
- **Low Power Consumption:** Typically draws 200 µA per amplifier.  
- **Wide Supply Voltage Range:** Operates from ±5V to ±18V.  
- **Low Input Bias Current:** Typically 3 pA.  
- **Low Input Offset Voltage:** Typically 1 mV.  
- **High Slew Rate:** 3 V/µs typical.  
- **Unity-Gain Stable:** Suitable for voltage-follower applications.  
- **Low Noise:** 25 nV/√Hz typical at 1 kHz.  

### **Package:**  
- **DIP-8 (Dual In-Line Package, 8-pin).**  

### **Applications:**  
- Precision integrators  
- Sample-and-hold circuits  
- Low-noise amplifiers  
- High-impedance sensor amplifiers  
- Battery-powered devices
