Description and Introduction

JFET-Input Operational Amplifiers Low Supply Current High Speed The LF355H is a high-speed JFET input operational amplifier manufactured by National Semiconductor Corporation (NSC). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** ±5V to ±18V  
- **Input Offset Voltage:** 3 mV (max)  
- **Input Bias Current:** 30 pA (typ)  
- **Input Offset Current:** 3 pA (typ)  
- **Input Resistance:** 1012 Ω (typ)  
- **Slew Rate:** 12 V/µs (typ)  
- **Gain Bandwidth Product:** 4 MHz (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:**  
- The LF355H is a monolithic JFET-input operational amplifier with low input bias current and offset current.  
- It is designed for high-speed, high-input-impedance applications.  
- The device features internal phase compensation and a high slew rate.  

### **Features:**  
- **Low Input Bias Current:** 30 pA (typ) due to JFET input stage.  
- **High Input Impedance:** 1012 Ω (typ).  
- **Wide Bandwidth:** 4 MHz (typ) gain bandwidth product.  
- **Fast Slew Rate:** 12 V/µs (typ).  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **Internal Compensation:** No external components required for stability.  
- **High CMRR and PSRR:** Ensures performance in noisy environments.  

The LF355H is commonly used in precision integrators, sample-and-hold circuits, and other high-impedance analog applications.
