Description and Introduction

Quad Comparator The LM239A is a quad differential comparator manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Supply Current:** 0.8mA (typical) per comparator  
- **Input Offset Voltage:** 2mV (typical), 5mV (maximum)  
- **Input Bias Current:** 25nA (typical)  
- **Response Time:** 1.3μs (typical) for 5mV overdrive  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Type:** Open-collector  
- **Output Sink Current:** 16mA (minimum)  

### **Description:**  
The LM239A is a quad independent precision voltage comparator designed to operate from a single power supply over a wide voltage range. It features low input offset voltage, low supply current, and fast response time, making it suitable for industrial, automotive, and consumer applications.  

### **Features:**  
- **Wide Supply Voltage Range:** 2V to 36V (single supply)  
- **Low Input Bias Current:** 25nA (typical)  
- **Low Input Offset Voltage:** 2mV (typical)  
- **Low Supply Current Drain:** 0.8mA per comparator  
- **Common-Mode Input Voltage Range Includes Ground**  
- **Differential Input Voltage Range Equal to Supply Voltage**  
- **Open-Collector Output for Wire-OR Connections**  
- **ESD Protection:** 2kV (HBM)  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official STMicroelectronics documentation.
