QST QMA7981 linear speed sensor

QMA7981 is a new generation product developed based on QMA6981. It is specially designed for smart mobile terminals,Internet of Things,and wearable applications. This generation of products has ultra-low power consumption,high sensitivity,anti-stress performance and zero drift,which is stronger and more stable. excellent features. The product has an LGA package with dimensions of 2*2*0.95 mm3,I2C&SPI digital communication,14-bit analog-to-digital conversion,and the data output frequency can be as high as 2000Hz. The standby current is as low as 1μA and the operating current is as low as 1.7μA; this product has a measuring range of +/-32g and can provide ultra-high resolution better than 0.2mg. In addition to providing conventional acceleration detection functions,QMA7981 optimizes somatosensory computing and detection through a built-in ASIC to support intelligent somatosensory applications. Especially in the application scenarios of wearable devices,QMA7981 will demonstrate the advantages of convenient system embedding/integration,faster response,and lower energy consumption,becoming the perfect solution for intelligent sports health systems and intelligent gesture systems
