Description and Introduction

High-Speed, Micropower, Low-Voltage, SOT23, Rail-to-Rail I/O Comparators The MAX992EUA is a high-side current-sense amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 28V  
- **Input Common-Mode Voltage Range:** 4V to 28V  
- **Gain Accuracy:** ±0.5% (max)  
- **Gain Options:** 20V/V, 50V/V, 100V/V  
- **Bandwidth:** 250kHz (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**  
- The MAX992EUA is a precision, high-side current-sense amplifier designed for monitoring current in automotive, industrial, and power management applications.  
- It operates with a wide input common-mode voltage range, making it suitable for high-voltage systems.  
- The device provides a ground-referenced output proportional to the load current, eliminating the need for level-shifting circuits.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 4V to 28V.  
- **Low Offset Voltage:** Ensures accurate current measurement.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Gain Accuracy:** ±0.5% max error for precise current sensing.  
- **Small Footprint:** Available in an 8-pin µMAX package for space-constrained designs.  
- **Reverse Battery Protection:** Withstands -5V to +28V on the input.  

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

Application Scenarios & Design Considerations

High-Speed, Micropower, Low-Voltage, SOT23, Rail-to-Rail I/O Comparators

Alternative Part Number

  • LT1720CMS8 --: Dual high-speed comparator with similar supply range and push-pull output, pin-compatible MSOP-8 footprint, widely available.
  • TLV3201AIDBVR --: Low-power dual comparator with rail-to-rail inputs and push-pull output, suitable functional replacement in SOT-23/MSOP packages.
  • LM393DR --: Industry-standard dual comparator with open-collector output; requires pull-up but is a low-cost, widely stocked functional alternative.
  • TLV3502AIDGK --: Dual 4.5ns rail-to-rail comparator with comparable supply voltage and pin-compatible MSOP-8 footprint.
  • ADCMP602BRMZ --: Dual high-speed comparator offering similar propagation delay and supply range, suitable alternative in MSOP-8 package.
