Description and Introduction

Low Power Low Offset Voltage Dual Comparators The LM393 is a dual differential comparator manufactured by Texas Instruments (TI) and NEC.  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 36V (single supply) or ±1V to ±18V (dual supply)  
- **Low Supply Current:** 0.4mA (typical) per comparator  
- **Low Input Bias Current:** 25nA (typical)  
- **Low Input Offset Current:** 5nA (typical)  
- **Input Offset Voltage:** 2mV (typical)  
- **Common-Mode Input Voltage Range:** Includes ground (0V)  
- **Differential Input Voltage Range:** Equal to the supply voltage  
- **Output Saturation Voltage:** 250mV (typical) at 4mA  
- **Operating Temperature Range:**  
  - **TI:** -40°C to +125°C  
  - **NEC:** -40°C to +85°C  

### **Descriptions and Features:**  
- **Dual Comparator:** Contains two independent voltage comparators  
- **Open-Collector Outputs:** Allow for flexible output configurations  
- **Wide Supply Voltage Range:** Suitable for battery-powered and industrial applications  
- **Low Power Consumption:** Ideal for portable and energy-efficient designs  
- **High Accuracy:** Low input offset voltage and current  
- **Reliable Performance:** Stable operation over a wide temperature range  

Both TI and NEC offer the LM393, with slight variations in specifications depending on the manufacturer's datasheet.
