December 3, 2020-AMS AG, the world's leading high-performance sensor solutions provider, today announced the launch of the world's most accurate digital temperature sensor AS6221.
AS6221 can achieve a measurement accuracy of ±0.09°C in the temperature range of 20°C to 42°C, which is suitable for measuring human body and skin temperature. In today's market, there is no other similar digital temperature sensor that can achieve a measurement accuracy better than ±0.10°C.
AS6221 adopts WLCSP package, the size is only 1.5 mm x 1 mm, the power consumption is 6A when the output data rate is 4Hz, and the power consumption is only 0.1A in standby mode.
This compact, ultra-low-power, high-performance sensor is very suitable for battery-powered portable wearable electronic devices, such as health status or fitness monitoring wristbands, and smart watches. In addition, in high-end computing systems and servers, it can also be used to precisely adjust the processor's operating conditions to maximize system throughput while avoiding overheating.
The launch of AS6221 has consolidated AMS AG’s position in the health monitoring technology market. In addition, AMS AG has also launched the blood oxygen saturation measurement sensor AS7038RB, biosensor AS7030B, devices for medical imaging systems, and applications in this field. Existing products such as NanEye series image sensors for endoscopes.
Alexander Rensink, Manager of the Position Sensor Business Unit of AMS AG, said: "In high-end consumer products, such as smart watches and health detection wristbands, skin temperature is a key indicator. Therefore, design engineers need to invest a lot of time and energy to try Achieve and verify high-precision temperature measurement under all working conditions. The AS6221 launched today makes this work easier, not only provides more accurate measurement results, but also simplifies the temperature sensor integration in the system, and can Flexible support for a certain range of working voltage."
In the entire supply voltage range of 1.7V to 3.6V, AS6221 can achieve high-precision measurement. In contrast, other similar high-precision competitive products on the market can only achieve the highest accuracy at a certain voltage point, and the accuracy of the measurement results in the remaining operating voltage range will be reduced.
The measurement conversion time of the AMS AG sensor is as short as 35ms. Its full operating temperature range is -40°C to 125°C.
Convenient digital output options
AS6221 is a complete digital temperature sensor system without calibration or linearization. It provides measurement output through a standard I2C interface and contains eight I2C addresses.
AS6221 also provides an alarm function to remind users when the temperature exceeds a threshold. The temperature value of the alarm function can be set by the host processor through the device's register instruction set.
Samples of the AS6221 temperature sensor are now available.
