Description and Introduction

Low Voltage Reference The ICL8069DMSQ is a precision voltage reference IC manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Reference Voltage:** 1.23V (typical)  
- **Initial Accuracy:** ±0.5% (max)  
- **Temperature Coefficient:** 10ppm/°C (max)  
- **Operating Current:** 50µA (typical)  
- **Line Regulation:** 0.1%/V (typical)  
- **Load Regulation:** 0.1%/mA (typical)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** Hermetically sealed TO-46 metal can  

### **Descriptions:**
- The ICL8069DMSQ is a low-power, precision voltage reference designed for high-accuracy applications.  
- It provides a stable 1.23V output with excellent temperature stability and low power consumption.  
- The device is suitable for use in analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision measurement systems.  

### **Features:**
- **Low Power Consumption:** Operates at just 50µA, making it ideal for battery-powered applications.  
- **High Stability:** Low temperature coefficient ensures minimal drift over temperature variations.  
- **Wide Operating Range:** Functions reliably across industrial and military temperature ranges.  
- **Hermetic Packaging:** The TO-46 metal can provides robust protection against environmental factors.  
- **Low Noise:** Designed for precision applications requiring minimal output noise.  

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

Application Scenarios & Design Considerations

Low Voltage Reference

Alternative Part Number

  • LM385BZ-1.2 --: 1.2V micropower voltage reference with similar tolerance and temperature drift, widely available and pin-compatible in most through-hole designs.
  • LT1004CZ-1.2 --: Precision 1.2V shunt reference with comparable initial accuracy and low drift, suitable drop-in replacement for the ICL8069 in many circuits.
  • LM4040DIZ-1.2 --: 1.2V precision micropower shunt reference offering similar performance and a different series naming, good alternative when supply is limited.
  • LM4040DIZ-2.5 --: Precision 2.5V shunt voltage reference with tight tolerance and low temperature coefficient, a common functional replacement for the ICL8069 2.5V reference.
  • TL431ACLP --: Adjustable shunt reference that can be set to 2.5V, widely available and cost-effective, suitable for many circuits using the ICL8069.
  • LM336Z-2.5 --: 2.5V shunt voltage reference diode with similar operating principle and package options, usable as a drop-in style substitute in many designs.
