GENERAL DESCRIPTION
The ADXL288 is a dual-axis accelerometer with signal-
conditioned 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
package with an exposed pad. The ADXL288 can operate
at 3.3 V and 5 V and is specified for operation from −40°C
to +105°C.
