There are a wide variety of temperature sensors available, from thermocouples to thermistors to RTDs, each with its own strengths: RTDs are accurate, thermistors are low cost, and thermocouples have wide operating ranges, for instance. However, these sensors all need additional signal conditioning or linearization to be useful in a system. Silicon-based IC sensors are emerging as a viable alternative for consumer, industrial, and automotive temperature ranges.
The trend is to add signal processing to sensors, and with IC temperature sensors it's possible to include some or all of the signal processing on the same IC as the sensor itself, creating complete ...
