Description and Introduction

Low-Cost / Micropower / Precision / 3-Terminal / 1.2V Voltage Reference The MAX6120ESA is a precision voltage reference manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 2.5V  
- **Initial Accuracy:** ±0.2%  
- **Temperature Coefficient (Tempco):** 3ppm/°C (typical)  
- **Output Current:** 10mA (max)  
- **Supply Voltage Range:** 4.5V to 40V  
- **Dropout Voltage:** 2.5V (typical)  
- **Long-Term Stability:** 20ppm/1000 hours  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA)  

### **Descriptions:**  
The MAX6120ESA is a high-precision, low-noise voltage reference with ultra-low temperature drift. It is designed for applications requiring stable voltage references, such as data acquisition systems, industrial instrumentation, and precision analog circuits.  

### **Features:**  
- Ultra-low noise: 3µVp-p (0.1Hz to 10Hz)  
- Low dropout voltage (2.5V)  
- High output current capability (10mA)  
- Low quiescent current (300µA typical)  
- Excellent line and load regulation  
- No external capacitor required for stability  
- Reverse-battery protection  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

Low-Cost / Micropower / Precision / 3-Terminal / 1.2V Voltage Reference

Alternative Part Number

  • REF3012AIDBZT --: Series voltage reference in SOT-23 with similar 1.25V output and low quiescent current, a common drop-in for MAX6120 in many designs.
  • LM4040AIM3-1.2 --: Precision 1.2V shunt reference in SOT-23, widely available and electrically close to the MAX6120 for low-power reference applications.
  • ADR121ARTZ-REEL7 --: High-accuracy 1.25V series reference in SOT-23, offering comparable initial accuracy and temperature drift as an upgrade path.
  • ADR1581ARTZ-REEL7 --: Low-noise 1.25V series reference in SOT-23, offering comparable accuracy and stability for precision applications.
