STTS22HTR

STTS22HTR is a low-voltage, ultralow-power, 0.5°C accuracy I²C/SMBus 3.0 temperature sensor. It is a high-accuracy, digital temperature sensor offering high performance over the entire operating temperature range. It is a bandgap temperature sensor coupled with an A/D converter, signal processing logic, and an I²C/SMBus 3.0 interface all in a single ASIC. This sensor is housed in a small 2 x 2 x 0.50mm 6-lead UDFN package with exposed pad down for a better temperature match with the surrounding environment. It is factory calibrated and requires no additional calibration efforts on the customer side. The units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated in accordance with the IATF 16949:2016 standard. Typical applications are wearable devices, smart home automation, asset and goods tracking, smartphones, HVAC, refrigerators, air humidifiers, portable consumer devices, white goods, thermostats.
