Description and Introduction

Single Supply Quad Comparator The LM239DR2 is a quad differential comparator manufactured by ON Semiconductor.  

### **Specifications:**  
- **Manufacturer:** ON Semiconductor  
- **Type:** Quad Differential Comparator  
- **Number of Channels:** 4  
- **Supply Voltage Range:** 2V to 36V (Single Supply) or ±1V to ±18V (Dual Supply)  
- **Input Offset Voltage:** 2mV (Typical), 5mV (Maximum)  
- **Input Bias Current:** 25nA (Typical)  
- **Response Time:** 1.3μs (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-14  

### **Descriptions:**  
The LM239DR2 consists of four independent precision voltage comparators designed to operate from a single power supply over a wide voltage range. It features low input bias current, low offset voltage, and fast response time, making it suitable for industrial, automotive, and consumer applications.  

### **Features:**  
- Wide single-supply voltage range (2V to 36V) or dual supplies (±1V to ±18V)  
- Low input bias current: 25nA (Typical)  
- Low input offset voltage: 2mV (Typical)  
- Fast response time: 1.3μs (Typical)  
- Compatible with TTL, CMOS, and MOS logic  
- ESD protection on all pins  
- High output sink current capability (16mA)  
- Pb-free and RoHS compliant  

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