ams OSRAM 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 via a 2-wire digital bus with other devices. The sensors are designed for use in applications requiring high measurement accuracy, including skin temperature. The AS6221 and AS6221T Sensors can also be used to replace PTC resistors and are ideally suited for mobile/battery-powered applications thanks to the high-temperature accuracy and ultra-low power consumption.
The AS6221 and AS6221T sensors provide ease of use and feature a factory-calibrated sensor, integrated linearization, and the possibility of using eight different I2C addresses, enabling the use of eight AS6221 or AS6221T devices on one bus. The temperature sensor system also offers alert functionality, which triggers an interrupt to protect devices from excessive temperatures.
The ams OSRAMAS6221T Digital Temperature Sensors are calibrated according to NIST, and an ISO/IEC-17025 accredited laboratory calibrates the verification equipment.
