3-axis low-power MEMS accelerometer provides buffered analog X, Y, and Z outputs in a 12-pin QFN package. The device supports selectable ±2 g and ±8 g measurement ranges and uses a fixed 0.75 V zero-g output offset. High-bandwidth operation provides typical bandwidth of 2.7 kHz on the X and Y axes and 600 Hz on the Z axis. It operates from a 1.71 V to 3.6 V supply with typical active current of 180 µA and shutdown current of 30 nA. The package is RoHS compliant, lead-free, halogen-free, and MSL 1 rated.
