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
conditioned outputs available via a 16-bit SPI interface. Identical,
512 kHz data interpolation rate
independent X and Y sense structures are implemented to create
Sensor frequency response down to dc
a high performance, high integrity acceleration sensing system.
On-demand electromechanical self-test
The X and Y acceleration channels have a nominal ful -scale
Fully differential circuitry for high resistance to EMI/RFI
range of ±120 g and a bandwidth of 408 Hz. The acceleration
Independent x- and y-axis sense structures for robust
data is provided as a 12-bit, twos complement word with a
FMEA performance
resolution of 62.5 mg/LSB.
Independent x- and y-axis arming thresholds Low noise: 1 LSB rms typical
The ADXL288 is available in a 16-lead, narrow-body SOIC
Qualified for automotive applications
package with an exposed pad. The ADXL288 can operate
Temperature range: −40°C to +105°C
at 3.3 V and 5 V and is specified for operation from −40°C
3.3 V and 5 V operation
to +105°C.
