Description and Introduction

Low Power Low Offset Voltage Quad Comparator The LM239AJ is a quad differential comparator manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Input Bias Current:** 25nA (typical)  
- **Low Input Offset Current:** 5nA (typical)  
- **Input Offset Voltage:** 2mV (typical), 5mV (maximum)  
- **Response Time:** 1.3μs (typical) for 5mV overdrive  
- **Operating Temperature Range:** -25°C to +85°C  
- **Output Type:** Open-collector  
- **Package:** 14-pin DIP (Dual In-line Package)  

### **Descriptions:**  
The LM239AJ consists of four independent precision voltage comparators designed for single or dual-supply operation. It features low input offset voltage and bias current, making it suitable for precision applications. The open-collector output allows for flexible interfacing with different logic levels.  

### **Features:**  
- Wide single or dual supply voltage range  
- Low input bias and offset currents  
- Low output saturation voltage  
- Compatible with TTL, CMOS, and MOS logic  
- ESD diodes on inputs for added protection  

This device is commonly used in industrial, automotive, and consumer applications where precise voltage comparisons are required.
