MCP6V01RD-TCPL

MCP6V01RD-TCPL is an MCP6V01 based Thermocouple Auto-Zeroed Reference Design board to demonstrates how to use a difference amplifier system to measure electromotive force (EMF) voltage at the cold junction of 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). MCP6V01 operational amplifiers has input offset voltage correction for very low offset and offset drift. These devices have a wide bandwidth product and strongly reject switching noise. They are unity gain stable, have no 1/f noise, and have good PSRR and CMRR. These products operate with a single supply voltage as low as 1.8V and are designed in an advanced CMOS process.

• Use a difference amplifier system as an analog sensor conditioning circuit
• Use the K-type thermocouple to sense temperature
• Use MCP9800 temperature sensor for cold junction compensation
• Use the USB interface to transfer data to PC
• Test points for bench work
