Description
AI
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 ±120gand 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.APPLICATIONSImpact sensingShock detection
