AIS326DQTR Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the AIS326DQTR?
  The recommended power-on sequence is to apply VDDIO before VDD. This ensures that the internal voltage regulators are properly powered up.
• How do I configure the interrupt pins to trigger on specific acceleration thresholds?
  The interrupt pins can be configured to trigger on specific acceleration thresholds by setting the INT1 and INT2 threshold registers (0x23-0x26) and enabling the corresponding interrupt sources (0x2A-0x2B).
• What is the maximum sampling rate of the AIS326DQTR?
  The maximum sampling rate of the AIS326DQTR is 1.6 kHz, but it can be adjusted to lower rates by configuring the ODR (Output Data Rate) register (0x2C).
• How do I calibrate the AIS326DQTR to improve its accuracy?
  The AIS326DQTR can be calibrated by applying a known acceleration (e.g., 1g) and adjusting the sensitivity and offset registers (0x13-0x16) to achieve the desired accuracy.
• What is the purpose of the self-test feature in the AIS326DQTR?
  The self-test feature (ST 0x3A) allows the user to verify the accelerometer's functionality by applying a known acceleration stimulus and checking the output.
