ams announced the launch of the AS6221, the world’s most accurate digital temperature sensor. The AS6221 achieves measurement accuracy of ±0.09°C, over a temperature range from 20°C to 42°C, making it ideal for the measurement of human body or skin temperature. No competing digital temperature sensor on the market today can achieve accuracy better than ±0.10°C.
The digital temperature sensor AS6221 is housed in a WLCSP package with a footprint of just 1.5mm x 1mm, and draws 6µA at an output data rate of 4Hz. Stand-by current is just 0.1µA.
This compact and low-power sensor is well suited to battery-powered portable and wearable devices, such as premium lifestyle or fitness monitoring wristbands, and smart watches. In high-end computing systems and servers, it also enables the precise regulation of the operation of the processor to maximize system throughput while avoiding overheating (more info).
