MCP9600 Thermocouple Electromotive Force (EMF) to Temperature Converter

Last modified by Microchip on 2023/11/09 09:03

The MCP9600 is a fully integrated thermocouple Electromotive Force (EMF) to degree Celsius converter with integrated cold-junction compensation. The MCP9600 supports eight thermocouple types (K, J, T, N, S, E, B, and R). It also provides user-programmable registers, adding design flexibility for various temperature-sensing applications. The registers allow user-selectable settings, such as low-power modes for battery-powered applications, an adjustable digital filter for fast transient temperatures, and four individually programmable temperature alert outputs, which can be used to detect multiple temperature zones.

MCP9600 Thermocouple EMF to °C Converter Demo & Evaluation Boards (ADM00665)

The MCP9600 Evaluation Board is used to digitize the thermocouple EMF voltage to degree Celsius with +/-1°C accuracy. Users can easily evaluate all the device features using a Type K thermocouple. The device also supports Types J, T, N, E, B, S, and R. Each of these types is evaluated by replacing the Type K thermocouple connector with the corresponding connectors (not included).
