Description and Introduction

Ultra-Low-Power / Open-Drain / Single/Dual-Supply Comparators The **MAX982ESA** is a low-power, high-performance operational amplifier (op-amp) manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±2.5V to ±6V (Dual Supply), 5V to 12V (Single Supply)  
- **Input Offset Voltage:** 1mV (max)  
- **Input Bias Current:** 10nA (max)  
- **Gain Bandwidth Product:** 1MHz  
- **Slew Rate:** 0.5V/µs  
- **Quiescent Current:** 500µA (per amplifier)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The MAX982ESA is a **precision, low-power op-amp** designed for applications requiring high accuracy and low power consumption.  
- It is **unity-gain stable**, making it suitable for buffer and signal conditioning applications.  
- The device features **low input offset voltage and bias current**, ensuring high DC accuracy.  

### **Features:**
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Rail-to-Rail Output Swing:** Maximizes dynamic range in single-supply applications.  
- **Unity-Gain Stable:** No external compensation required.  
- **Wide Supply Voltage Range:** Supports both single and dual-supply operation.  
- **Low Input Offset Voltage:** Ensures precision in DC-coupled circuits.  

The MAX982ESA is commonly used in **sensor interfaces, medical devices, portable instrumentation, and audio processing circuits**.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LTC1540CS8 --: Comparator with internal reference in SO-8, functionally similar to MAX982 and pin-compatible in most designs.
  • TLV3012AIDBVR --: Low-power comparator with integrated reference, suitable replacement for battery-powered comparator applications.
  • LM393DR --: Widely available dual comparator in SO-8; requires external reference but is a common low-cost substitute.
  • TLV3011IDBVR --: Low-power comparator with open-drain output in SOT-23, suitable functional replacement when package flexibility is acceptable.
