Description and Introduction

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators The MAX971CSA+T is a high-performance, low-power operational amplifier (op-amp) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (now part of Analog Devices)  
- **Part Number:** MAX971CSA+T  
- **Package:** 8-SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** 0°C to +70°C  
- **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 (GBWP):** 10MHz  
- **Slew Rate:** 5V/µs  
- **Output Current:** ±30mA  
- **Quiescent Current:** 3.5mA per amplifier  
- **Number of Channels:** 2 (Dual Op-Amp)  
- **Common-Mode Rejection Ratio (CMRR):** 90dB (min)  
- **Power Supply Rejection Ratio (PSRR):** 90dB (min)  

### **Descriptions:**  
The MAX971CSA+T is a dual, high-speed, low-noise operational amplifier designed for precision applications. It offers excellent performance with low distortion and high bandwidth, making it suitable for audio, signal conditioning, and instrumentation applications. The device operates from a wide supply voltage range and is available in an 8-pin SOIC package.

### **Features:**  
- Low input offset voltage (0.5mV max)  
- High gain bandwidth (10MHz)  
- Low noise (8nV/√Hz at 1kHz)  
- Low distortion (THD: 0.0006%)  
- Rail-to-rail output swing  
- High output current (±30mA)  
- Stable with capacitive loads up to 100pF  
- Low power consumption (3.5mA per amp)  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • LM393M --: Dual comparator in SOIC-8 with similar open-collector output and low supply current, a common drop-in substitute for the MAX971 comparator function.
  • TLV3201AIDBVR --: Low-power single comparator in SOT-23 with rail-to-rail input, suitable replacement when board layout allows a smaller package.
  • LT1716CS5 --: Micropower comparator with open-drain output and wide supply range, offering comparable performance for battery-powered comparator applications.
  • LT1017CS8#PBF --: Low-power comparator with similar supply range and open-drain output, pin-compatible in many designs.
  • TLV3011IDBVR --: Micropower comparator with integrated reference, suitable replacement for low-voltage comparator applications.
  • LM393DR --: Widely available dual comparator with similar function, though pinout and supply range should be verified.
