Single Supply Temperature Sensing with Thermocouples
There is a variety of temperature sensors on the market all of which meet specific
application needs. The most common sensors used to solve these application problems
include the thermocouple, Resistive Temperature Detector (RTD), Thermistor, and
silicon-based sensors. For an overview and comparison of these sensors, refer
to Microchip AN679, "Temperature Sensing Technologies". This application note focuses on circuit solutions that use thermocouples in the design. The signal conditioning path for the thermocouple system will be discussed in this application note followed by complete application circuits.
