Description and Introduction

Single General Purpose Voltage Comparator 5-SOT-23 -40 to 85 The LM397MF/NOPB is a single general-purpose voltage comparator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Supply Current:** 0.4mA (typical)  
- **Input Offset Voltage:** 2mV (max)  
- **Response Time:** 1.3μs (typical)  
- **Input Bias Current:** 25nA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LM397 is a high-speed, low-power voltage comparator with an open-collector output.  
- It is designed for single-supply operation but can also operate with dual supplies.  
- The device features low input offset voltage and fast response time, making it suitable for precision applications.  

### **Features:**  
- **Wide Supply Voltage Range:** Compatible with both single and dual supplies.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Open-Collector Output:** Allows flexible output voltage levels.  
- **ESD Protection:** Provides robustness against electrostatic discharge.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This comparator is commonly used in applications like level detection, oscillators, and analog-to-digital conversion.
