The MCP6V01 Thermocouple Auto-Zeroed Reference Design (MCP6V01RD-TCPL) 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).

The MCP6V01/2/3 family of operational amplifiers has input offset voltage correction for very low offset and offset drift. These devices have a wide gain bandwidth product (1.3 MHz, typical) 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, while drawing 300 μA/amplifier (typical) of quiescent current.

Key Applications: Portable Instrumentation, Sensor Conditioning, Temperature Measurement, DC Offset Correction, Medical Instrumentation
