AS6221 & AS6221T Digital Temperature Sensors

Infineon Technologies AS6221 and AS6221T Digital Temperature Sensors consist of a Si-bandgap temperature sensor, an ADC, and a digital signal processor. These digital temperature sensors communicate with other devices via a 2-wire digital bus. The sensors are designed for use in applications requiring high measurement accuracy, including skin temperature. The Infineon Technologies AS6221 and AS6221T Sensors can also replace PTC resistors and are ideally suited for mobile/battery-powered applications, thanks to the high-temperature accuracy and ultra-low power consumption.
