These applications include wearables and, in particular, hearables and clinical point-of-care applications.
MLX90632 is based upon Melexis' established far infrared (FIR) technology that is based on all objects emitting heat radiation. Miniaturized far-infrared sensors can be sensitive to thermal disturbances, but MLX90632 mitigates this through compensation algorithms to deliver high levels of thermal stability. The medical-grade MLX90632 has been optimized for the normal human body temperature range, where it offers medical-grade accuracy of ±0.2°C.
The device comes in a 3x3x1mm QFN package, which integrates the sensor element, signal processing, digital interface and optics.
