Description and Introduction

Ultra Low-Power, Low-Cost Comparators with 2eference The MAX931CPA is a low-power, single-supply comparator manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about the part:

### **Manufacturer:**  
- **MAXIM** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Supply Voltage Range:** +2.5V to +11V (single supply)  
- **Quiescent Current:** 5µA (typical)  
- **Propagation Delay:** 3µs (typical)  
- **Input Offset Voltage:** 2mV (max)  
- **Input Bias Current:** 10nA (max)  
- **Common-Mode Input Voltage Range:** (V−) to (V+ − 1.5V)  
- **Output Type:** Open-drain  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**  
- The MAX931CPA is a low-power, high-speed comparator optimized for single-supply operation.  
- It features an open-drain output, allowing flexible interfacing with different logic levels.  
- Designed for battery-powered applications due to its ultra-low current consumption.  

### **Features:**  
- **Low Power Consumption:** 5µA typical supply current.  
- **Single-Supply Operation:** Works from +2.5V to +11V.  
- **Open-Drain Output:** Compatible with various logic levels.  
- **High-Speed Response:** 3µs propagation delay.  
- **Wide Input Voltage Range:** Supports rail-to-rail input operation.  
- **Internal Hysteresis:** Improves noise immunity.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LM393N --: Dual comparator with similar open-collector output and DIP-8 package; widely available and pin-compatible in most comparator circuits.
  • TLV3011 --: Low-power comparator with internal reference, functionally similar to the MAX931's reference-comparator role, though package and pinout may differ.
  • LT1017 --: Micropower dual comparator offering comparable low-supply-current operation and open-collector outputs as a functional substitute.
  • TLV3011ACDBVR --: Low-power comparator with reference, similar function to the MAX931's internal reference, though in SOT-23 package requiring an adapter.
  • LT1017CN8 --: Micropower dual comparator in DIP-8 with similar supply range and open-collector output, suitable as a functional replacement.
