MCP9604 4-Channel Thermocouple Conditioning IC

The MCP9604 from Microchip Technology is a fully integrated thermocouple conditioning IC designed for precise temperature measurement across multiple channels. It converts thermocouple EMF signals to degrees Celsius using NIST ITS-90 coefficients, ensuring high accuracy and reliability in demanding environments.

This device supports eight common thermocouple types (K, J, T, N, S, E, B, and R) and includes cold-junction compensation, open/short-circuit detection, and programmable alert outputs. Its I²C-compatible interface simplifies integration with microcontrollers, reducing design complexity and eliminating the need for multiple discrete components. With a typical accuracy of ±0.5°C and a maximum of ±1.5°C, the MCP9604 is ideal for industrial and embedded systems requiring robust thermal monitoring.
