Description and Introduction

Low Power JFET Input Operational Amplifier The LF441 is a JFET-input operational amplifier manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** ±4V to ±18V  
- **Input Offset Voltage:** 3 mV (max)  
- **Input Bias Current:** 50 pA (max)  
- **Input Offset Current:** 25 pA (max)  
- **Input Resistance:** 10¹² Ω (typical)  
- **Common-Mode Rejection Ratio (CMRR):** 100 dB (min)  
- **Slew Rate:** 13 V/µs (typical)  
- **Gain Bandwidth Product:** 3 MHz (typical)  
- **Power Consumption:** 2.5 mA (typical per amplifier)  
- **Operating Temperature Range:** -25°C to +85°C  

### **Descriptions:**  
- The LF441 is a low-power, high-performance JFET-input operational amplifier.  
- It is designed for applications requiring high input impedance, low input bias current, and low power consumption.  
- The device is internally compensated for stable operation in unity-gain configurations.  

### **Features:**  
- **JFET Input:** Provides very high input impedance and low input bias current.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Slew Rate:** Ensures fast response in signal processing.  
- **Wide Supply Voltage Range:** Operates from ±4V to ±18V.  
- **Internal Compensation:** Eliminates the need for external compensation components.  
- **Low Noise:** Suitable for precision analog applications.  

For exact performance characteristics, refer to the official Texas Instruments datasheet.
