Description:Board Mount Temperature Sensors +/- 1.5C Thermocouple to I2C converter in 5mmx5mm QFN. This device has Opens/Shorts pin detection. This device supports K, J, T, N, S, E, B, and R type thermocouples.
The datasheet provides general guidelines, but for optimal performance, it's recommended to place the MCP9601T-E/MX close to the thermocouple, use a ground plane, and keep the analog and digital traces separate. A 4-layer PCB with a dedicated analog ground plane is recommended.
The MCP9601T-E/MX has an internal cold junction compensation (CJC) circuit, but it may require calibration for high-accuracy applications. Calibration involves measuring the CJC voltage and adjusting the internal voltage reference. Refer to the application note AN2217 for calibration procedures.
The maximum thermocouple wire length depends on the specific application and noise environment. As a general guideline, keep the thermocouple wire length as short as possible (less than 10 feet) and use a shielded, twisted-pair cable to minimize noise pickup. Use a thermocouple wire type that matches the thermocouple type (e.g., K-type, J-type, etc.).
To minimize EMI and RFI, use a shielded enclosure, keep the thermocouple wire and PCB traces as short as possible, and use a common-mode filter (e.g., a ferrite bead) on the thermocouple wires. Ensure the PCB layout follows good EMI/RFI design practices, such as separating analog and digital circuits.
To ensure proper operation, power up the MCP9601T-E/MX in the following sequence: 1) Apply VDD, 2) Apply VREF, and 3) Apply the thermocouple voltage. This sequence helps prevent latch-up and ensures the internal voltage reference is stable.
