AS6221T-AWLM.

AS6221T 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 high measurement accuracy is needed, for example measuring the skin temperature. Beside these applications, it can also be used to replace PTC resistors. The high temperature accuracy and an ultra-low power consumption (low operation and quiescent current) makes the AS6221T ideally suited for mobile/battery powered applications. The AS6221T is an easy to integrate and use solution, featuring a factory-calibrated sensor, integrated linearization and the possibility to use 8 different I²C addresses, enabling to use eight AS6221T devices on one bus. Applications fitness/health wristbands, personal computers, wearables, HVAC, replacement of PTCs, electronic equipment, tablets, convertibles and laptop.
