How does a silicon temperature (temp) sensor IC actually measure temperature? These ICs take advantage of the basic temperature-dependent behavior of silicon PN junctions. If you have two PN junctions ...
Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are LTC3880, LTC3883 and LTC2974. Accurate temperature sensing depends on proper PNP selection, ...
To understand the concept of a remote temperature sensor and how it differs from a local temperature sensor, it’s best to first review some basics of temperature-sensor ICs. A silicon ...
