Description and Introduction

High-Speed, Low-Power Voltage Comparators The **MAX902ESD+** is a high-speed, low-power comparator manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Supply Voltage Range:** +2.7V to +5.5V  
- **Low Supply Current:** 1.4µA (typical)  
- **Propagation Delay:** 3µs (typical)  
- **Input Offset Voltage:** 1mV (max)  
- **Input Bias Current:** 1nA (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 14-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The **MAX902ESD+** is a **single, low-power, high-speed comparator** with a push-pull output.  
- It is designed for **battery-powered and portable applications** due to its ultra-low power consumption.  
- The device features **rail-to-rail input capability**, making it suitable for low-voltage operation.  

### **Features:**  
- **Ultra-Low Quiescent Current (1.4µA)**  
- **Rail-to-Rail Input Voltage Range**  
- **Push-Pull Output Stage (No External Pull-Up Resistor Required)**  
- **Internal Hysteresis for Noise Immunity**  
- **Wide Supply Voltage Range (2.7V to 5.5V)**  
- **Small Footprint (14-pin SOIC Package)**  

This comparator is commonly used in **battery monitoring, threshold detection, and portable electronics** due to its low power and high-speed performance.  

(Note: Always refer to the latest datasheet from Analog Devices for updated specifications.)

Application Scenarios & Design Considerations

High-Speed, Low-Power Voltage Comparators

Alternative Part Number

  • LM311M --: Industry-standard single comparator with similar open-collector output and supply range, widely available and pin-compatible in SOIC-14.
  • LT1011CS8 --: Precision single comparator offering comparable response time and input characteristics, suitable drop-in for many MAX902 applications.
  • TL3116CD --: Fast single comparator with similar propagation delay and output configuration, good functional substitute when exact MAXIM part is unavailable.
