Analog Devices EVAL-CN0391-ARDZ 64-bit ADC Evaluation Board for CN0391 for AD7124-8, ADP7118, Thermocouple Arduino

The circuit can process up to four independent thermocouple channels, and the software linearization algorithms support eight different types of thermocouples (B, E, J, K, N, R, S, and T). The four thermocouples can be connected in any combination, and resistance temperature detectors (RTDs) on each thermocouple channel provide cold junction compensation (CJC). No extra compensation is needed. Thermocouple measurements using this system cover the full operating range of the various types of thermocouples.The circuit has a standard serial peripheral interface (SPI) connection to Arduino-compatible platform boards for rapid prototyping. With a USB to UART interface and open source firmware, the EVAL-CN0391-ARDZ can be easily adapted to a variety of thermocouple applications
