EVAL-CN0271-SDPZ is K-Type Thermocouple Measurement System with Integrated Cold Junction Compensation Evaluation Board. The AD8495 thermocouple amplifier provides a simple, low cost solution for measuring Ktype thermocouple temperatures, including cold junction compensation. A fixed gain instrumentation amplifierin the AD8495 amplifies the small thermocouple voltage to provide a 5 mV/°C output. The high common-mode rejection of the amplifier blocks commonmode noise that the long thermocouple leads can pick up. For additional protection, the high impedance inputs of the amplifier make it easy to add extra filtering.
