Description and Introduction

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators The MAX971ESA is a low-power, high-performance operational amplifier (op-amp) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±2.25V to ±6V (Dual Supply), 4.5V to 12V (Single Supply)  
- **Input Offset Voltage:** 0.5mV (max)  
- **Input Bias Current:** 10nA (max)  
- **Gain Bandwidth Product (GBW):** 8MHz  
- **Slew Rate:** 4V/µs  
- **Output Current:** 50mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The MAX971ESA is a precision, low-noise op-amp designed for applications requiring high-speed performance with low power consumption.  
- It features rail-to-rail output swing, making it suitable for single-supply operation.  
- The device is optimized for battery-powered and portable applications due to its low quiescent current.  

### **Features:**
- **Rail-to-Rail Output Swing:** Ensures maximum dynamic range in low-voltage applications.  
- **Low Noise:** 10nV/√Hz input noise voltage.  
- **Low Power Consumption:** 1.2mA supply current per amplifier.  
- **Unity-Gain Stable:** No external compensation required.  
- **Short-Circuit Protected:** Enhanced reliability in harsh conditions.  
- **Wide Supply Range:** Supports both single and dual-supply configurations.  

The MAX971ESA is commonly used in audio amplifiers, signal conditioning, active filters, and data acquisition systems.

Application Scenarios & Design Considerations

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators

Alternative Part Number

  • LT1716CS5 --: Pin-compatible single comparator with similar supply range and open-drain output, widely available and a direct functional substitute.
  • TLV3011ACDBVR --: Low-power single comparator with open-drain output and comparable response time, suitable drop-in replacement in most circuits.
  • LMV7219M5 --: Fast low-voltage comparator with push-pull output; check output stage compatibility but electrically close and commonly used as an alternative.
  • LT1114CS8 --: Quad low-power precision comparator with similar supply range and open-drain output, direct functional replacement in most MAX971 applications.
  • LM339N --: Industry-standard quad comparator with wide supply range and open-collector outputs, widely available and pin-compatible in many designs.
  • TLV3404IPW --: Quad micropower comparator with low supply current and open-drain outputs, suitable when lower power consumption is required.
