Temperatursensoren

The AS6223 IC is a high accuracy digital temperature sensor system that communicates via a 2-wire digital bus with other devices. It consists of a Si bandgap temperature sensor, an ADC and a digital signal processor.This sensor is especially designed to be used in applications where a small form factor with good performance is required, for example in mobile devices measuring the PCB and electronics temperature.The very small form factor and ultra-low power consumption (low operation and quiescent current) makes the AS6223 ideally suited for mobile/battery powered applications.The AS6223 is an easy to integrate and use solution, featuring a factory-calibrated sensor, integrated linearization and the possibility to use 4 different I²C addresses, enabling to use up to four AS6223 devices on one bus.The AS6223 production test setup is calibrated according to NIST and the verification equipment is calibrated by an ISO/IEC-17025 accredited laboratory.The AS6223 fulfills NIST traceability.

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.。 More information about Longevity Program

The AS621x family is a complete digital sensor system, designed for the needs of various markets. It features 8 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. It is a fully calibrated and linearized sensor system that is easy to integrate in any digital system. The family has 3 members (AS6212, AS6214 & AS6218) with different temperature accuracies to give customers the best option for their needs. The highest performing AS6212 has an accuracy of +/- 0.2°C from -10°C to 65 °C. It provides a resolution of 16 bit over the wide temperature range 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 1.71V to 3.6V. For powersensitive applications, the device can enter a low-power wait mode with 0.1μA current consumption.The AS6212, AS6214 and AS6218 production test setup is calibrated according NIST and the verification equipment is calibrated by an ISO/IEC-17025 accredited laboratory.。 More information about Longevity Program
