Description and Introduction

Low power quad voltage comparator The LM339EDT is a quad voltage comparator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Type:** Quad Differential Comparator  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Supply Current:** 0.8mA (typical)  
- **Input Offset Voltage:** 2mV (typical)  
- **Input Bias Current:** 25nA (typical)  
- **Response Time:** 1.3μs (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-14  

### **Descriptions:**  
The LM339EDT consists of four independent precision voltage comparators designed to operate from a single power supply over a wide voltage range. It features low input offset voltage and low supply current, making it suitable for battery-powered applications.  

### **Features:**  
- **Wide Single-Supply Voltage Range:** 2V to 36V  
- **Low Input Bias Current:** 25nA  
- **Low Input Offset Voltage:** 2mV  
- **Low Supply Current Drain:** 0.8mA (independent of supply voltage)  
- **Output Compatible with TTL, MOS, and CMOS**  
- **ESD Protection:** 2kV (HBM)  
- **Open-Collector Outputs for Flexible Configurations**  

This device is commonly used in industrial, automotive, and consumer applications for voltage monitoring, level detection, and signal conditioning.
