ams OSRAM AS6221T
Digital temperature sensor with best-in-class accuracy
The AS6221 is a high accurate digital temperature sensor with an accuracy of up to ±0.09°C, which is ideal for healthcare applications, wearables and devices requiring high-performance thermal information. As a complete digital sensor system, AS6221 requires no calibration or linearization. It provides measurement outputs via a standard I²C interface. The sensor supports eight I²C addresses avoiding bus conflicts in multi-sensor use cases. The ultra-small size (WLCSP 1.5 mm x 1.0 mm) and very low power consumption enable accurate body/skin temperature measurements in very small health and lifestyle monitoring products.
