MCP9600 Sensor Conditioning ICs - Microchip

Thermocouple Sensor Conditioning

Thermocouple interfacing requires expertise in sensitive analog design, mixed-signal systems, and high-order mathematics for realizing temperature from the small voltage (μV) output of a thermocouple. Microchip’s fully integrated thermocouple Electromotive Force (EMF) to degree celsius converter with cold-junction compensation greatly simplifies the design process by integrating all needed functions in one package, reducing time to market.

MCP9600 Thermocouple EMF to Degree Celsius Converter

The MCP9600 is a fully integrated thermocouple EMF to degree celsius converter with cold-junction compensation. The MCP9600 supports eight thermocouple types (K, J, T, N, S, E, B, and R). It 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 that can be used to detect multiple temperature zones.
