Description and Introduction

Monolithic Sample and Hold Circuit The LF398 is a monolithic sample-and-hold circuit manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Sample-and-Hold IC  
- **Operating Voltage:** ±5V to ±18V  
- **Hold Step (ΔV):** 0.5mV (typical)  
- **Acquisition Time:** 6µs (to 0.01% for 10V step)  
- **Aperture Time:** 150ns (max)  
- **Aperture Jitter:** 50ns (max)  
- **Droop Rate:** 1mV/ms (max)  
- **Input Bias Current:** 30pA (max)  
- **Gain Bandwidth Product:** 3.5MHz (typical)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Description:**  
The LF398 is a high-performance sample-and-hold amplifier designed for precision data acquisition applications. It features low droop rate, fast acquisition time, and high accuracy, making it suitable for analog-to-digital conversion, signal processing, and instrumentation systems.  

### **Features:**  
- **Low Hold Step:** Ensures minimal voltage deviation during hold mode.  
- **Fast Acquisition Time:** Enables rapid sampling of input signals.  
- **High Input Impedance:** Reduces loading effects on the source.  
- **Low Droop Rate:** Maintains held voltage with minimal decay.  
- **Wide Operating Voltage Range:** Supports ±5V to ±18V supplies.  
- **Internal Hold Capacitor Connection:** Simplifies external component requirements.  
- **TTL, PMOS, and CMOS Compatible Logic Inputs:** Ensures flexible control interface.  

This information is strictly based on the available technical details for the LF398 from National Semiconductor.
