MCP9600 Thermocouple Electromotive Force (EMF) to Temperature Converter
small-MCP9600-MQFN-20.png

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 Converter Evaluation Board

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 +/-1C 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).

Features

  • Fully integrated thermocouple measurement using MCP9600
  • No prior thermocouple measurement experience is necessary
  • Direct readout of measured temperature
  • Programmable temperature set points with hysteresis
  • 1.5°C accuracy over -40°C to +125°C

Benefits

  • No prior experience in thermocouple measurement is necessary
  • Simplifies design, reduces development time and costs
  • Minimizes effects of system noise and EMI
  • Shutdown mode reduces overall power consumption
  • Thermal Management Utility works in conjunction with demo board to provide real-time measurements and configuration of device parameters.
  • I2C Bus available for host connectivity
  • User programmable Thermal Alerts, reduces microcontroller computation overhead
  • MIKROE #2811 CLICK BOARD and MCC drivers and development environment allows rapid prototyping and evaluation.
