LIS352AR Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the LIS352AR?
  The recommended power-on sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
• How do I configure the LIS352AR for low-power mode?
  To configure the LIS352AR for low-power mode, set the LPEN bit in the CTRL_REG1 register to 1. This reduces the current consumption to approximately 10 μA.
• What is the maximum acceleration range of the LIS352AR?
  The LIS352AR has a maximum acceleration range of ±2g, ±4g, ±8g, or ±16g, depending on the range selection made through the CTRL_REG2 register.
• How do I adjust the sensitivity of the LIS352AR?
  The sensitivity of the LIS352AR can be adjusted by changing the full-scale range through the CTRL_REG2 register. A higher range setting reduces the sensitivity, while a lower range setting increases the sensitivity.
• What is the purpose of the SELFTEST bit in the CTRL_REG1 register?
  The SELFTEST bit enables a self-test mode that applies a known acceleration to the sensor, allowing the user to verify the device's functionality and calibration.
