Description and Introduction

Quad Comparator The LM239AMX is a quad differential comparator manufactured by Fairchild Semiconductor (now part of ON Semiconductor).  

### **Specifications:**  
- **Number of Channels:** 4 (Quad)  
- **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 +85°C  
- **Output Type:** Open Collector  
- **Package:** SOIC-14  

### **Descriptions:**  
- The LM239AMX is a low-power, quad voltage comparator designed for single or dual-supply operation.  
- It features a wide operating voltage range and low input bias current, making it suitable for industrial and automotive applications.  
- The open-collector output allows for flexible interfacing with different logic levels.  

### **Features:**  
- **Low Input Bias Current:** 25nA (Typical)  
- **Low Input Offset Voltage:** 2mV (Typical)  
- **Wide Supply Voltage Range:** 2V to 36V (Single Supply)  
- **High Output Sink Current:** 16mA  
- **ESD Protection:** Up to 2kV (Human Body Model)  
- **Common-Mode Input Voltage Range Includes Ground**
