Description and Introduction

Quad Comparator The LM339A from STMicroelectronics is a quad voltage comparator with the following specifications, descriptions, and features:  

### **Specifications:**  
- **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), 5mV (maximum)  
- **Input Bias Current:** 25nA (typical)  
- **Response Time:** 1.3μs (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Saturation Voltage:** 250mV (typical) at 4mA  
- **Open-Collector Outputs** (allows wired-OR connections)  

### **Description:**  
The LM339A 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, 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  
- **Low Input Offset Voltage:** 2mV  
- **Low Power Consumption:** 0.8mA per comparator  
- **Open-Drain Outputs** for flexible interfacing  
- **ESD Protection:** 2kV (HBM)  
- **AEC-Q100 Qualified** for automotive applications  

The LM339A is available in various packages, including SO-14, TSSOP-14, and PDIP-14.
