AIS328DQTR Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VDDIO first, followed by VDD. This ensures that the internal regulators are properly powered up before the analog circuitry.
  • The interrupt pins can be configured through the INT1_CFG and INT2_CFG registers. The interrupt sources can be selected through the INT1_SRC and INT2_SRC registers. Refer to the datasheet for the specific bit settings.
  • The AIS328DQTR can measure accelerations up to ±16g. However, the maximum acceleration range can be adjusted through the FS_SEL register to ±2g, ±4g, or ±8g.
  • The AIS328DQTR has a built-in self-test feature that can be used to calibrate the sensor. The self-test feature applies a known acceleration to the sensor and measures the output. The offset and sensitivity can be adjusted based on the self-test results.
  • The typical current consumption of the AIS328DQTR is 140 μA at 2.5 V and 25°C. However, the current consumption can vary depending on the operating mode and the output data rate.
