3-axis accelerometer QMA6981

Product details:

QMA6981 is specially developed for the application in smart mobile terminals and IoT; it has small size, low power consumption, high sensitivity and stable zero drift.  LGA in 2*2*0.95 mm3. I2C digital communication. Multiple working modes and 32-level FIFO can be dynamically configured. 10-bit A/D conversion, output data rate 2000Hz. QMA6981 detects acceleration and also has smart motion algorithms embedded in ASIC. When used in a wearable device, it can be more conveniently embedded in the system, responds faster, and consumes lower power. The company has further started the research and development of smart motion applications based on QMA6981, and provides solutions to smart sports & health systems and smart hand gesture systems.
