Description and Introduction

Single/Dual/Quad High-Speed, Ultra Low-Power, Single-Supply TTL Comparators The MAX909ESA is a low-power, single-supply comparator manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** +2.5V to +5.5V  
- **Low Quiescent Current:** 1.5µA (typical)  
- **Propagation Delay:** 3µs (typical)  
- **Input Offset Voltage:** ±1mV (max)  
- **Input Bias Current:** 1pA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The MAX909ESA is a micropower comparator optimized for single-supply operation.  
- It features a push-pull output stage, eliminating the need for an external pull-up resistor.  
- Designed for battery-powered and portable applications due to its ultra-low power consumption.  

### **Features:**  
- Ultra-low power consumption (1.5µA typical)  
- Single-supply operation (2.5V to 5.5V)  
- Rail-to-rail input capability  
- Push-pull output stage  
- No external pull-up resistor required  
- Small 8-pin SOIC package  

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

Application Scenarios & Design Considerations

Single/Dual/Quad High-Speed, Ultra Low-Power, Single-Supply TTL Comparators

Alternative Part Number

  • LM393M --: Dual differential comparator in SOIC-8, pin-compatible with MAX909 and widely available as a general-purpose replacement.
  • LM2903M --: Dual comparator in SOIC-8 with similar open-collector output and supply range, a common drop-in alternative for MAX909.
  • NE521D --: Dual high-speed differential comparator in SOIC-8 offering comparable function and speed for MAX909 applications.
  • LM293D --: Dual comparator in SOIC-8 offering comparable input offset and supply voltage range, widely available and pin-compatible with the MAX909.
  • TLV1702DGK --: Low-power dual comparator in VSSOP-8 with rail-to-rail inputs, suitable functional replacement when lower power consumption is desired.
