Infineon Technologies AS6223 Digital Temperature Sensors
Infineon Technologies AS6223 Digital Temperature Sensors are high-accuracy sensor systems that communicate via a two-wire digital bus with other devices. The AS6223 IC includes a Si bandgap temperature sensor, an ADC, and a digital signal processor. The sensor is specifically designed for applications that require a compact form factor and good performance, such as mobile devices that measure PCB and electronic temperatures. The tiny form factor and ultra-low power consumption (low operation and quiescent current) make the AS6223 ideal for mobile/battery-powered applications.
The Infineon AS6223 Digital Temperature Sensors are easy to integrate and use, featuring a factory-calibrated sensor, integrated linearization, and the possibility to use four different I2C addresses, allowing the use of up to four AS6223 devices on one bus. The AS6223 production test setup is calibrated in accordance with NIST standards, and an ISO/IEC 17025-accredited laboratory calibrates the verification equipment. The AS6223 accomplishes NIST traceability.
