Description and Introduction

DUAL AND QUAD DIFFERENTIAL COMPARATORS The LM2903 is a dual differential comparator manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments  

### **Description:**  
The LM2903 is a dual, independent, high-gain voltage comparator designed to operate from a single power supply over a wide range of voltages. It is capable of comparing two input voltages and providing a digital output indicating which input is higher.  

### **Key Features:**  
- **Dual Comparator:** Contains two independent comparators in a single package.  
- **Wide Supply Voltage Range:** Operates from **2V to 36V** (single supply) or **±1V to ±18V** (dual supply).  
- **Low Supply Current Drain:** Typically **0.4 mA per comparator** (independent of supply voltage).  
- **Low Input Bias Current:** **25 nA** (typical).  
- **Low Input Offset Current:** **5 nA** (typical).  
- **Low Input Offset Voltage:** **2 mV** (typical).  
- **Common-Mode Input Voltage Range:** Includes ground.  
- **Differential Input Voltage Range:** Equal to the supply voltage.  
- **Output Compatible with TTL, MOS, and CMOS Logic.**  
- **Open-Collector Output:** Allows for wired-OR configurations.  
- **Operating Temperature Range:** **-40°C to +125°C** (LM2903).  

### **Applications:**  
- Voltage level detection  
- Battery-powered systems  
- Limit comparators  
- Analog-to-digital converters  
- Oscillators  
- Peak detectors  

### **Package Options:**  
Available in various packages including **SOIC, PDIP, TSSOP, and VSSOP**.  

This information is based solely on the manufacturer's datasheet and technical specifications.
