AS6200C Temperature SensorCold chain digital temperature sensor
The AS6200C is a complete digital sensor system designed to fulfill the challenges of cold chain applications in storage and transportation. It is very well suited for data loggers complying with EN12830:1999 class 1 standard as well as enriching the performance of domestic and commercial refrigerators. The AS6200C provides a fully calibrated and linearized sensor system that can easily be accessed via an I²C interface. It provides a resolution of 12-bit with its highest accuracy of ±0.2°C from +20°C to -10°C. The integrated alarm functionality enables micro controller wake up calls on defined temperature thresholds. An internal voltage regulator enables stable accuracy independent of the supply voltage between 1.8 to 3.6V. For power sensitive applications, the device can enter a low-power wait state with 0.1μA current consumption.

New highly accurate digital temperature sensor from ams helps designers of cold-storage equipment to meet demanding error budget targets
New AS6200C sensor provides easy-to-use digital output and requires no user calibration or linearization
The superior performance of the AS6200C makes it easier for designers of refrigerators and data loggers in cold-chain storage equipment to meet demanding targets for system-level accuracy.
The AS6200C’s measurements are accurate to ±0.2°C between -20°C and 10°C, the temperature range over which storage equipment for perishable goods operates. The sensor’s accuracy is guaranteed over the device’s supply voltage range of 1.8V to 3.6V.
In temperature control and temperature logging applications, the total error budget is made up of multiple components. By minimizing the error at the point of measurement, the designer gains extra headroom for other error and noise sources, such as the heat generated by board-mounted com-ponents. The use of the highly accurate AS6200C gives the designer more flexibility to modify other elements of the system design while keeping total error below a specified maximum level.
The AS6200C integrates a sensor front end, 12-bit analog-to-digital converter and digital logic in a small WL-CSP package. It provides a digital output over an I2C interface to any host microcontrol-ler. The device performs on-board digital signal processing, which means that it needs no user calibration, and its linearized output requires no compensation by an external microcontroller.
The AS6200C is intended for use in equipment for storing and transporting food, pharmaceuticals, flowers and other perishable goods, as well as in domestic and commercial refrigerators. It is very well suited to data loggers that comply with the EN12830:1999 class 1 standard.
The new device extends the ams family of small, accurate digital temperature sensor ICs, joining the AS6200 sensor, which achieves peak accuracy between 0°C and 65°C.
