ams AS6204 Temperature Sensor

The AS6204 is a complete digital sensor system, designed for the needs of high-performance consumer electronics. It is based on the well-proven AS6200 design, but with additional I²C addresses to serve complex design needs. This is especially useful in the prototyping phase of a product where several heat sensitive areas might need monitoring but without needing to reserve additional systems application processor resources. The AS6204 is a fully calibrated and linearized sensor system that is easy to integrate in any digital system. It provides a resolution of 12 bit over the wide temperature range <br> from -40°C to 125°C. The integrated alarm functionality enables micro-controller wake-up calls on defined temperature thresholds. An internal voltage regulator allows stable accuracy independent of the supply voltage between 1.8V to 3.6V. For powersensitive applications, the device can enter a low-power wait mode with 0.1μA current consumption.

ams AS6221 Temperature Sensor

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.<div><span style="color: inherit; font-family: inherit; font-weight: 300;"><br>The AS6221 production test setup is calibrated according NIST and the verification equipment is calibrated by an ISO/IEC-17025 accredited laboratory.</span><br></div>
