STS40-BD1B-R3

The STS4x is Sensirion’s state-of-the-art, 4th generation, highly accurate digital temperature sensor series, boasting industry-leading lead times. It is a fully digital, highly cost-efficient 16bit temperature sensor platform that is available in different accuracy classes, currently represented by the STS40. The STS4x temperature sensor range features enhanced signal processing, three distinctive I2C addresses and communication speeds of up to 1MHz. Moreover, the dual-flat no-leads (DFN) package has a footprint of only 1.5 x 1.5mm2 while retaining a height of 0.5mm, which allows for an easy integration of the STS4x series into various applications. Additionally, the wide supply voltage range of 1.08 to 3.6V and low current consumption of 0.4µA for a typical average current at 1 measurement per second enables battery-driven designs. Thanks to Sensirion’s CMOSens® Technology, the STS4x temperature sensor benefits from the high-tech engineering of a wide range of sensor components.
