Temperature-to-Bits: One IC for All Sensor Types, 0.1°C Conformity
Temperature measurement is not new. Galileo invented a rudimentary thermometer capable of detecting temperature changes, and two hundred years later, Seebeck discovered the thermocouple. Given the long history of temperature measurement and its extensive use today, one would think that accuracy problems were all but eliminated. Not so. Even though methods for extracting temperature from sensor elements are well known, accurately measuring temperatures to better than 0.5°C or 0.1°C accuracy remains a challenge. The LTC2983 is a groundbreaking, high performance integrated temperature measurement system that directly digitizes thermocouples, RTDs, thermistors and diodes with laboratory grade precision. It features high accuracy, an easy sensor interface and tremendous flexibility.
