The STTS22H is a band gap temperature sensor coupled with an A/D converter, signal processing logic and an IC/SMBus 3.0 interface all in a single ASIC. This sensor is housed in a small 2 x 2 x 0.50 mm 6-lead UDFN package with exposed pad down for a better temperature match with the surrounding environment. The STTS22H is factory calibrated and requires no additional calibration efforts on the customer side. The STTS22H 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. DS12606 - Rev 6 page 2/29
