The MCP6V01 Thermocouple Auto-Zero Reference Design (Part Number: MCP6V01RD-TCPL) demonstrates how to use a differential amplifier system to measure the electromotive force (EMF) voltage at the cold junction of a thermocouple to accurately measure the temperature at the hot junction of the thermocouple. This is achieved with the MCP6V01 auto-zeroing op amp due to its ultra-low offset voltage (VOS) and high common-mode rejection ratio (CMRR).
Features:
• Uses a differential amplifier system as analog sensor conditioning circuit
• Uses K-type thermocouple for temperature detection
• Temperature range -100°C to +1000°C
• Uses MCP9800 temperature sensor for thermocouple cold junction compensation
• Uses
USB interface for transmission Data to PC
• Test points for benchmarking work
