Description and Introduction

+5V/Programmable Low-Dropout Voltage Regulator The MAX667CPA is a temperature sensor and cold-junction compensator manufactured by Maxim Integrated (now part of Analog Devices). Below are its factual specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (MAXI)  
- **Type:** Cold-Junction Compensated Thermocouple-to-Digital Converter  
- **Temperature Range:** 0°C to +1024°C (with K-type thermocouple)  
- **Resolution:** 12-bit (0.25°C)  
- **Supply Voltage:** 3.0V to 5.5V  
- **Current Consumption:** 1.5mA (typical)  
- **Interface:** SPI-compatible serial output  
- **Accuracy:** ±2°C (from 0°C to +700°C), ±3°C (from -20°C to 0°C and +700°C to +1024°C)  
- **Package:** 8-pin PDIP (Plastic Dual In-Line Package)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
The MAX667CPA is designed to convert the signal from a K-type thermocouple into a digital temperature reading while compensating for cold-junction effects. It integrates a thermocouple amplifier, ADC, and cold-junction compensation circuitry, simplifying temperature measurement in industrial, automotive, and consumer applications.  

### **Features:**  
- Cold-junction compensation integrated  
- Simple SPI-compatible serial interface  
- Converts K-type thermocouple signals to digital  
- No external components required for temperature measurement  
- Open thermocouple detection  
- Low power consumption  

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

Application Scenarios & Design Considerations

+5V/Programmable Low-Dropout Voltage Regulator

Alternative Part Number

  • LT1021DCN8-5 --: Precision 5V voltage reference in 8-pin DIP, functionally similar to MAX667 and widely available.
  • AD586KNZ --: High-precision 5V reference in DIP-8 package, suitable drop-in replacement for many MAX667 applications.
  • REF02CPZ --: 5V precision voltage reference in 8-pin DIP, comparable specifications and pinout for reference circuits.
  • AD586JN --: 5V precision voltage reference in 8-pin DIP with comparable initial accuracy and low drift, suitable replacement for MAX667CPA in most reference applications.
