Description and Introduction

Ultra Low-Power, Single/Dual-Supply Comparators The MAX921ESA is a high-speed, low-power operational amplifier (op-amp) manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** ±4.5V to ±18V (Dual Supply) or +9V to +36V (Single Supply)  
- **Input Offset Voltage:** 1mV (max)  
- **Input Bias Current:** 50nA (max)  
- **Gain Bandwidth Product (GBW):** 20MHz  
- **Slew Rate:** 10V/µs  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Input Common-Mode Voltage Range:** Includes Ground (Single-Supply Operation)  
- **Output Current:** ±30mA (Short-Circuit Protected)  
- **Quiescent Current:** 5mA (typical)  

### **Descriptions:**  
The MAX921ESA is a precision, high-speed operational amplifier designed for applications requiring wide bandwidth and low power consumption. It is optimized for single or dual-supply operation and provides excellent performance in signal conditioning, active filtering, and data acquisition systems.  

### **Features:**  
- **Wide Supply Voltage Range:** Supports both single and dual-supply configurations.  
- **High Slew Rate:** 10V/µs enables fast signal response.  
- **Low Input Offset Voltage:** Ensures accuracy in precision applications.  
- **Unity-Gain Stable:** No external compensation required.  
- **Rail-to-Rail Output Swing:** Maximizes dynamic range in single-supply applications.  
- **Low Power Consumption:** 5mA typical quiescent current.  
- **Short-Circuit Protection:** Prevents damage during output faults.  

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

Application Scenarios & Design Considerations

Ultra Low-Power, Single/Dual-Supply Comparators

Alternative Part Number

  • LT1715CMS8 --: Single/dual comparator with similar low-power, low-voltage operation and 8-pin MSOP package; a strong functional drop-in candidate from a different series.
  • TLV3201AIDBVR --: Low-power push-pull comparator with rail-to-rail input, comparable supply range and response time, available in small SOT-23 package.
  • LM393DR --: Widely available dual comparator with similar open-collector output and supply range; pinout differs so layout adaptation is required, but it is a common low-cost substitute.
  • LTC1440CS8 --: Single/dual supply micropower comparator with internal reference, functionally similar to MAX921 and pin-compatible in many designs.
  • TLV3011IDBVR --: Low-power comparator with integrated voltage reference, suitable drop-in replacement for battery-powered comparator applications.
