Description and Introduction

LOW POWER QUAD VOLTAGE COMPARATOR The LM139AD is a quad voltage comparator manufactured by AMD (Advanced Micro Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **AMD (Advanced Micro Devices)**  

### **Specifications:**  
- **Number of Channels:** 4 (Quad Comparator)  
- **Supply Voltage Range:** ±1V to ±18V (Dual Supply), 2V to 36V (Single Supply)  
- **Input Offset Voltage:** 2mV (Typical), 5mV (Maximum)  
- **Input Bias Current:** 25nA (Typical)  
- **Response Time:** 1.3μs (Typical)  
- **Output Type:** Open Collector  
- **Operating Temperature Range:** -25°C to +85°C (Industrial Grade)  
- **Package Type:** SOIC-14  

### **Descriptions:**  
- The LM139AD is a quad independent precision voltage comparator designed for single or dual supply operation.  
- It features low input offset voltage and bias current, making it suitable for high-accuracy applications.  
- The open-collector outputs allow for flexible interfacing with different logic levels and loads.  

### **Features:**  
- **Wide Supply Voltage Range:** Compatible with both single and dual power supplies.  
- **Low Input Bias Current:** Minimizes errors in high-impedance circuits.  
- **Fast Response Time:** Suitable for high-speed switching applications.  
- **Open-Collector Outputs:** Can drive loads such as relays, lamps, or logic circuits.  
- **High Voltage Gain:** Ensures precise comparison even with small input differences.  

This information is strictly based on the available knowledge base for the LM139AD by AMD.
