Product features

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.The AS6221, is a complete digital sensor system, 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 of the sensor (WLCSP 1.5 mm x 1.0 mm) enables accurate body/skin temperature measurements in very small health and lifestyle monitoring products.In addition to the high accuracy and the small form factor, the AS6221 offers a very low power consumption, for example measuring with 4 samples/s, the current consumption is only 6 µA. The sensor has 4 different automatic acquisition modes and keeps the high accuracy over the full supply range from 1.71 to 3.6 V.An integrated alert functionality triggers an interrupt to the micro controller when a temperature threshold is exceeded. The temperature threshold for the alert function can be adjusted in a device register.

The AS6221 production test setup is calibrated according NIST and the verification equipment is calibrated by an ISO/IEC-17025 accredited laboratory.
