Description and Introduction

Micropower, Ultra-Small, Single/Dual/Quad Single-Supply Comparators The MAX9021AUK+T is a high-speed, low-power comparator manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Propagation Delay:** 4.5ns (typical)  
- **Quiescent Current:** 1.4mA (typical)  
- **Input Offset Voltage:** ±1mV (max)  
- **Input Bias Current:** 0.1μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-5  

### **Descriptions:**  
- The MAX9021AUK+T is a single, ultra-fast comparator optimized for low-voltage operation.  
- It features rail-to-rail input and output operation, making it suitable for precision applications.  
- Designed for high-speed signal processing in portable and battery-powered systems.  

### **Features:**  
- **High-Speed Operation:** 4.5ns propagation delay enables fast response times.  
- **Low Power Consumption:** 1.4mA typical supply current.  
- **Rail-to-Rail Inputs/Outputs:** Supports full dynamic range.  
- **Internal Hysteresis:** Improves noise immunity.  
- **Wide Supply Range:** Operates from 2.7V to 5.5V.  
- **Small Form Factor:** Available in a compact SOT23-5 package.  

This comparator is ideal for applications such as threshold detection, line receivers, and high-speed signal conditioning.

Application Scenarios & Design Considerations

Alternative Part Number

  • TLV3201AIDBVR --: Single comparators in SOT-23-5 with similar supply range and push-pull output; widely available and pin-compatible in function.
  • LMV7219M5/NOPB --: Fast single comparator in SOT-23-5 with push-pull output, comparable propagation delay and supply voltage, good drop-in functional replacement.
  • ADCMP600BRJZ-RL7 --: High-speed single comparator with push-pull output and similar supply range; alternative when faster switching is acceptable.
  • LMV7219M5 --: Low-power single comparator in SOT-23-5 with push-pull output and comparable propagation delay, widely used as an alternative to MAX9021.
  • ADCMP600BRJZ --: High-speed single comparator with push-pull output and similar supply voltage, suitable replacement when faster switching is acceptable.
