Description and Introduction

Low Power Low Offset Voltage Quad Comparators The LM339 from Texas Instruments (TI) is a quad differential comparator. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Number of Channels:** 4  
- **Output Type:** Open Collector  
- **Propagation Delay Time:** 1.3 µs (typical)  
- **Supply Voltage Range:** 2V to 36V  
- **Input Offset Voltage:** ±1 mV (typical), ±5 mV (maximum)  
- **Input Bias Current:** 25 nA (typical)  
- **Operating Temperature Range:** 0°C to +70°C (LM339), -40°C to +125°C (LM339A)  
- **Package Options:** PDIP, SOIC, TSSOP  

### **Description:**  
The LM339 consists of four independent voltage comparators designed to operate from a single power supply over a wide voltage range. It features low input bias current and offset voltage, making it suitable for precision applications. The open-collector outputs allow for flexible interfacing with other logic levels or higher voltage/current loads.  

### **Features:**  
- **Wide Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Input Bias Current:** 25 nA (typical)  
- **Low Input Offset Voltage:** ±1 mV (typical)  
- **Open-Collector Outputs:** Allow for wired-OR connections  
- **Low Power Consumption:** 0.8 mA per comparator (typical)  
- **ESD Protection:** Up to 2000V (HBM)  

This information is strictly factual and derived from TI's datasheet for the LM339.
