Product Summary

The STSC1 is a digital temperature sensor designed

especially for applications requiring a highly accurate

temperature measurement.

technology offers a complete sensor system on a single

chip, consisting of a bandgap temperature sensor, analog

and digital signal processing, A/D converter, calibration

data memory, and a digital communication interface

applications in even the most limited of spaces. The

sensor covers a temperature measurement range of –40

to 125 °C. The typical accuracy of the temperature

sensor is ±0.3°C. The operation voltage of 1.8 V and an

average power consumption below 8.6µW make the

STSC1 suitable for mobile or wireless applications

running on the tightest power budgets.
