- High temperature accuracy of ±0.09 °C (20...42 °C)
- Ultra-low-power consumption: 6 µA at 4 SPS (typ.) and 0.1 μA in standby (typ.)
- Small form factor WLCSP package: total size 1.5 × 1.0 mm
- No calibration or linearization required
The AS6221 is a highly accurate digital temperature sensor with an accuracy of 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. The ultra-small size of the sensor (WLCSP 1.5 x 1.0 mm) enables accurate body/skin temperature measurements in health and lifestyle monitoring products. In addition to the high accuracy and the small form factor, the AS6221 offers very low power consumption, e.g., measuring with 4 samples per second (SPS), the current consumption is only 6 μA.
