- Digital output with SPI/I2C interface (vs ADXL356BEZ)
Design Notes
The ADXL357BEZ requires a clean power supply. Place a 0.1 µF ceramic capacitor as close as possible to the VDD pin and a 1 µF capacitor on the VDD I/O pin. The supply voltage should be between 2.25V and 3.6V, and the digital interface voltage can be set independently via VDD I/O (1.8V to 3.6V). Avoid sharing the supply with high-current digital circuits to prevent noise coupling.
For optimal performance, use a solid ground plane under the device and minimize trace lengths to the microcontroller. The CLCC package has an exposed pad that should be soldered to the ground plane for thermal and mechanical stability. Ensure that the SPI/I2C lines are properly terminated and shielded if routed near high-frequency signals.
Do not exceed the absolute maximum ratings of 3.6V on VDD or VDD I/O. When using SPI, ensure the CS pin is properly pulled high when not in use. The device has an internal FIFO; configure it correctly to avoid data loss. Also, note that the ADXL357BEZ is sensitive to mechanical stress, so avoid mounting it near flexing PCB areas.
