The LTC2997 temperature-to-voltage converter integrates series resistance cancellation for 2.5V to 5.5V systems and measures a remote diode’s temperature with ±1°C accuracy or ...

Linear Technology's LTC2997 is a high accuracy temperature to voltage converter with built in series resistance cancellation for 2.5 to 5.5V systems.

The conversion normally requires significant amounts of energy in the form of high heat -- a temperature of at least 700 degrees Celsius, hot enough to melt aluminum at normal atmospheric pressure.
