TSYS02D-FAMILY Digital Temperature Sensors Product Description The TSYS02* is a single device, temperature sensor. It provides factory-calibrated data corresponding to the measured temperature. 2 The data is provided via I C interface. The temperature range is -40C ... +125C while the resolution is 2 0.01C. The TSYS02 can be interfaced to any microcontroller by an I C interface. The TDFN8 package provides smallest size and very fast time response.

If exceeded by even the smallest amount, instantaneous catastrophic failure can occur. And even if the device continues to operate satisfactorily, its life may be considerably shortened.
