Description and Introduction

Ultra Low-Power, Low-Cost Comparators with 2eference The **MAX931EPA** is a precision, low-power comparator manufactured by **Maxim Integrated**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Precision, Low-Power Comparator  
- **Supply Voltage Range:** +2.5V to +11V (Single Supply), ±1.25V to ±5.5V (Dual Supply)  
- **Quiescent Current:** 5µA (Typical)  
- **Response Time:** 3µs (Typical)  
- **Input Offset Voltage:** 1mV (Max)  
- **Input Bias Current:** 5nA (Max)  
- **Output Type:** Open-Drain  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP  

### **Descriptions:**
The **MAX931EPA** is a single, ultra-low-power comparator designed for precision applications. It features an open-drain output, making it suitable for interfacing with different logic levels. Its low quiescent current and fast response time make it ideal for battery-powered and portable devices.

### **Features:**
- **Ultra-Low Power Consumption:** Only 5µA supply current.  
- **Wide Supply Voltage Range:** Operates from +2.5V to +11V (single supply) or ±1.25V to ±5.5V (dual supply).  
- **Precision Performance:** Low input offset voltage (1mV max).  
- **Fast Response Time:** 3µs propagation delay.  
- **Open-Drain Output:** Allows flexible interfacing with different logic levels.  
- **Low Input Bias Current:** 5nA maximum.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **8-Pin PDIP Package:** Easy to use in through-hole PCB designs.  

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

Application Scenarios & Design Considerations

Ultra Low-Power, Low-Cost Comparators with 2eference

Alternative Part Number

  • LM393N --: Dual differential comparator in DIP-8, functionally similar to the MAX931 single comparator with internal reference; widely available and low cost.
  • TLV3011ACDBVR --: Comparator with integrated 1.242V reference in SOT-23, closely matching the MAX931's reference-comparator function for low-power designs.
  • LTC1540CS8 --: Micropower comparator with built-in reference in SO-8, similar low-power reference-comparator role as the MAX931, suitable as a direct functional substitute.
  • TLV3011 --: Comparator with integrated voltage reference in a small package, closely matching the MAX931's built-in reference feature.
  • LM311N --: General-purpose voltage comparator in DIP-8 with flexible supply range, a common substitute for Maxim comparator parts.
  • TLV3201IDR --: Low-power single comparator with push-pull output and fast response; suitable functional replacement when output stage and supply range are acceptable.
