Simple Interface Circuit for High-Resolution, Multichannel, Smart Temperature Sensing based on NTC Thermistors

摘要

A simple interface circuit for high-resolution, multichannel smart temperature sensing based on NTC thermistors is described in this paper. The circuit is based on the Universal Sensors and Transducers Interface integrated circuit designed by authors, which supplies three different interfacing modes for thermistors and has three popular digital serial interfaces. Such approach lets considerably reduce a time-to-market for various thermistor based sensor systems.
