Overview
The STTS22HTR is a low-voltage, ultralow-power digital temperature sensor produced by STMicroelectronics. This sensor offers high accuracy and performance across its entire operating temperature range. It is designed as a bandgap temperature sensor coupled with an A/D converter, signal processing logic, and an I²C/SMBus 3.0 interface, all integrated into a single ASIC. The sensor is housed in a compact 2 x 2 x 0.55 mm UDFN-6 package with an exposed pad for better thermal matching with the surrounding environment.
