STS35-DIS

Datasheet STS3x-DIS High-Accuracy Digital Temperature Sensor IC  Fully calibrated and linearized digital output  Wide supply voltage range, from 2.15 V to 5.5 V  I2C Interface with communication speeds up to 1 MHz and two user selectable addresses  Accuracy of up to  0.1 °C  Very fast start-up and measurement time  Tiny 8-pin DFN package  NIST traceability Product Summary The STS3x-DIS is Sensirion’s new high accuracy digital temperature sensor. It relies on the industry proven CMOSens® technology, providing for increased intelligence, reliability and improved accuracy specifications compared to its predecessors. Its functionality includes enhanced signal processing, two distinctive and user selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package has a footprint of 2.5 x 2.5 mm2 while keeping a height of 0.9 mm. This allows for integration of the STS3x-DIS into a great variety of applications. Additionally, the wide supply voltage range of 2.15 V to 5.5 V guarantees compatibility with a wide range of applications. All in all, the STS3x-DIS incorporates more than 15 years of Sensirion’s digital sensor know-how.

October 2019 - Version 5 1/18 Datasheet STS3x-DIS 1 1.1 Sensor Performance Temperature Sensor Performance Every STS3x is individually tested and calibrated and is identifiable by its unique serial number. The serial number is stored in an unchangeable OTP memory. For the temperature calibration, Sensirion uses transfer standards, which are subject to a scheduled calibration procedure. The calibration of the reference, used for the calibration of the transfer standards, is NIST traceable through an ISO/IEC 17025 accredited laboratory.
