The STTS22H is an ultra-low-power, high accuracy, digital temperature sensor offering high performance over the entire operating temperature range.
The STTS22H is a band gap 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 0.50 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.Key Features
