Data Sheet
ADXL288
FEATURES
GENERAL DESCRIPTION
120 g full-scale range
The ADXL288 is a dual-axis accelerometer with signal-
12-bit resolution at 62.5 mg/LSB
512 kHz data interpolation rate
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.
Sensor frequency response down to dc
On-demand electromechanical self-test
Fully differential circuitry for high resistance to EMI/RFI
Independent x- and y-axis sense structures for robust
FMEA performance
Independent x- and y-axis arming thresholds
Low noise: 1 LSB rms typical
Qualified for automotive applications
Temperature range: −40°C to +105°C
3.3 V and 5 V operation
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.
