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
