High Performance, Dual-Axis  
Digital Output Accelerometer  
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.
