Datasheet STS21 Temperature Sensor IC      Fully calibrated Digital output, I2C interface Low power consumption Excellent long term stability DFN type package – reflow solderable Product Summary STS21, the new temperature sensor of Sensirion is about to set new standards in terms of size and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1.1mm height it provides calibrated, linearized signals in digital, I2C format. Using the same CMOSens® technology as Sensirion‟s successful and industry proven SHT2x humidity and temperature sensors, the STS21 offers superior performance and reliability. The ±0.2°C temperature specification allows for implementation of the STS21 in applications with high demands on temperature accuracy.
