MCP9601 Thermocouple EMF to Temperature Converter

What Is a Thermocouple?​

• Two dissimilar metals joined at one end​
• Generates very small voltage that is used to calculate the temperature at the “HOT” junction​
• Generally used in harsh and extreme temperature environments
• Many standard Thermocouple types: K, J, T, N, S, E, B, and R​

What Is MCP9601?

MCP960X/L0X/RL0X converts thermocouple Electromotive Force (EMF) to degree Celsius with integrated cold-junction compensation. The temperature correction coefficients are derived from the National Institute of Standards and Technology (NIST) ITS-90 Thermocouple Database. The MCP9600/01 corrects the thermocouple nonlinear error characteristics of eight thermocouple types and outputs ±0.5°C/±1.5°C (Typ./Max.).
