MCP6V01RD-TCPL: Thermocouple Interface

The MCP6V01 Thermocouple Auto-Zeroed Reference Design demonstrates how to measure electromotive force (EMF) voltage at the cold junction of the thermocouple in order to accurately measure temperature at the hot junction. This can be done by using the MCP6V01 auto-zeroed op amp because of its ultra low offset voltage (VOS) and high common mode rejection ratio (CMRR).

Features:

• Uses a MCP6V01 difference amplifier as an analog sensor conditioning circuit
  

• Uses the K-type thermocouple to sense temperature
  

• Temperature range is from -100°C to +1000°C
  

• Uses the MCP9800 Temperature Sensor for cold junction compensation
  

• Uses the USB interface to transfer data to PC
  

• 14-Bit Resolution, 10-Bit ADC
  

• Test points for bench work
