Ultra low-power digital temperature sensor offers ±0.5°C accuracy

Housed in a 4mm2 package, the STTS22H from STMicroelectronics is factory-calibrated, and accuracy up to 125°C is verified with traceable equipment.

The STTS22H from STMicroelectronics is an ultra low-power digital temperature sensor which offers high performance over the entire operating-temperature range of -40°C to 125°C. Accuracy is a maximum ±0.5°C over a temperature range of -10°C to 60°C. 

The STTS22H is a band-gap temperature sensor coupled with an ADC, signal processing logic, and an I2C/SMBus 3.0 interface in a single chip. The sensor is housed in a small 2 mm x 2 mm x 0.50 mm 6-lead UDFN package with exposed pad down, giving a better temperature match with the surrounding environment.

The digital temperature sensor is factory-calibrated and requires no additional calibration on assembly into the application. STTS22H units are all tested on a production set-up which is traceable to National Institute of Standards and Technology (NIST) standards, and verified with equipment which is calibrated in accordance with the automotive IATF 16949:2016 standard.
