Description and Introduction

Dual Differential Comparator 8-SOIC -40 to 125 The LM2903DG4 is a dual differential comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Number of Channels:** 2  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Input Offset Voltage (Max):** 7mV  
- **Input Bias Current (Max):** 250nA  
- **Response Time (Typ):** 1.3μs  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  
- **Output Type:** Open Collector  
- **Common Mode Rejection Ratio (CMRR):** 80dB (Typ)  
- **Power Supply Rejection Ratio (PSRR):** 100dB (Typ)  

### **Description:**  
The LM2903DG4 is a dual, independent, high-gain voltage comparator designed for single or split-supply operation. It features low input bias current and offset voltage, making it suitable for precision applications. The open-collector output allows for flexible interfacing with other logic levels.  

### **Features:**  
- **Wide Supply Voltage Range:** Operates from 2V to 36V (single supply)  
- **Low Input Bias Current:** 250nA (Max)  
- **Low Input Offset Voltage:** 7mV (Max)  
- **Low Power Consumption:** 0.4mA per comparator (Typ)  
- **Open-Collector Outputs:** Compatible with TTL, CMOS, and other logic levels  
- **ESD Protection:** Up to 2kV (HBM)  
- **Industrial Temperature Range:** -40°C to +125°C  

This device is commonly used in battery-powered systems, industrial controls, and automotive applications due to its robustness and wide operating range.
