The ADXL288WBRDZ-RL 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 ADXL288WBRDZ-RL is available in a 16-lead, narrow-body SOIC package with an exposed pad. The ADXL288WBRDZ-RL can operate at 3.3 V and 5 V and is specified for operation from −40°C to +105°C.
