Description and Introduction

Low Power Low Offset Voltage Quad Comparator The LM139 from **INTERSIL.ST** is a quad independent precision voltage comparator. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **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) for a 5mV overdrive.  
- **Operating Temperature Range:** -55°C to +125°C.  
- **Output Current:** 16mA (sink capability).  
- **Package Options:** DIP-14, SOIC-14.  

### **Descriptions:**
- The LM139 consists of four independent 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 device is designed to operate over a wide voltage range and is compatible with TTL, CMOS, and MOS logic levels.  

### **Features:**
- **Wide Supply Voltage Range:** Supports both single and dual supplies.  
- **Low Input Bias Current:** Ensures minimal loading on the input source.  
- **Low Power Consumption:** Typically 0.8mA per comparator.  
- **High Output Sink Current:** Capable of driving relays, lamps, or other loads directly.  
- **ESD Protection:** Improved robustness against electrostatic discharge.  
- **Industry-Standard Pinout:** Compatible with other LM139/LM239/LM339 series comparators.  

This information is based solely on the manufacturer's datasheet for the LM139 from **INTERSIL.ST**.
