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.
Benefits of Sensirion’s CMOSens® Technology
High reliability and long-term stability
Industry-proven technology with a track record of
more than 15 years
Designed for mass production
High process capability
High signal-to-noise ratio

1 Sensor Performance
1.1 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.

1 The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurements at the stated repeatability and at constant ambient conditions. It
is a measure for the noise on the physical sensor output.
2 Temperature response times strongly depend on the type of heat exchange, the available sensor surface and the design environment of the sensor in the final
application.
