Description and Introduction

Single Comparator The LM311 is a voltage comparator manufactured by Texas Instruments (SEC). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** Single Supply: 3.5V to 30V, Dual Supply: ±1.75V to ±15V  
- **Input Offset Voltage:** 2mV (typical), 7.5mV (max)  
- **Input Bias Current:** 50nA (typical), 250nA (max)  
- **Response Time:** 200ns (typical)  
- **Output Current:** 50mA (sink or source)  
- **Operating Temperature Range:** 0°C to +70°C (commercial), -55°C to +125°C (military)  

### **Descriptions:**  
- The LM311 is a high-speed voltage comparator designed to operate from a wide range of power supplies.  
- It features a single open-collector output that can drive relays, lamps, or other loads.  
- The device is capable of comparing voltages and providing a digital output based on the comparison.  

### **Features:**  
- **Wide Supply Voltage Range:** Supports single and dual supply operation.  
- **Strobe Control:** Allows for output gating.  
- **High Output Current:** Can drive loads directly.  
- **Low Input Bias Current:** Ensures minimal loading on the input signal.  
- **Differential Input Voltage Range:** Matches the supply voltage range.  
- **TTL, DTL, ECL, MOS, and CMOS Compatible Outputs.**  

The LM311 is commonly used in applications such as level detection, analog-to-digital converters, and pulse generators.
