3.3 V and 5 V operation The ADXL288 is a dual-axis accelerometer with signalconditioned outputs available via a 16-bit SPI interface. Identical,
independent X and Y sense structures are implemented to create
a high performance, high integrity acceleration sensing system.
The X and Y acceleration channels have a nominal full-scale
range of ±120 g and a bandwidth of 408 Hz. The acceleration
data is provided as a 12-bit, twos complement word with a
resolution of 62.5 mg/LSB.
The ADXL288 is available in a 16-lead, narrow-body SOIC …
