Key Differentiators
- Differential quad sensor design rejects linear acceleration (vs ADXRS800WBRGZ)
- Wide supply voltage range (3.15V to 5.25V) (vs ADXRS646TBGZ)
- 16-bit SPI digital output (vs ADXRS800WBRGZ)
Design Notes
Ensure a clean and stable power supply for the ADXRS453BRGZ. Use a low-dropout regulator (LDO) to provide 3.3V or 5V, and place 0.1µF and 10µF decoupling capacitors close to the VDD pins. Avoid sharing the supply with high-current digital circuits to prevent noise coupling.
Maintain a solid ground plane beneath the sensor to minimize noise and ensure accurate measurements. Keep SPI traces short and shielded if possible. Avoid routing high-speed digital signals near the sensor to reduce electromagnetic interference.
Do not exceed the absolute maximum supply voltage of 5.25V. Ensure the SPI lines are properly terminated and the chip select is pulled high when not in use. The self-test pin (ST) should be tied to ground during normal operation to avoid unintended activation.
Compliance Information
RoHS compliant per datasheet and distributor listings. Not AEC-Q100 qualified; for automotive-grade, consider ADXRS800WBRGZ.
