Thermocouple Interface

ADI offers specialized precision thermocouple interface amplifiers that provide a simple and effective solution for measuring thermocouple temperatures. With features such as integrated cold junction compensation and a high-gain precision instrumentation amplifier, the AD849x and AD59x provide a complete signal conditioning system in one IC package customized for J and K type thermocouples. ADI’s thermocouple amplifiers provide a linear output voltage of 5mV/°C or 10mV/°C, and are suitable for use in laboratory environments as well as more hostile or uncontrolled environments, to measure a wide range of temperatures. These products will save you in cost, space, and unnecessary circuit design across a broad range of applications and industries.
