Title:
Precision Temperature Sensing with RTD Circuits
Name:
AN687

Author:
Bonnie C. Baker
Description:
This application note focuses on circuit solutions that use platinum RTDs in their design. Initially, the RTD temperature-sensing element will be compared to the negative temperature coefficient (NTC) thermistor, which is also a resistive temperature-sensing element. In this forum, the linearity of the RTD will be presented along with calibration formulas that can be used to improve the off-the-shelf linearity of the element.
