LIS3L02AQ3TR datasheet by STMicroelectronics

LIS3L02AQ3TR Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the LIS3L02AQ3TR?
  The recommended power-on sequence is to first apply VDD (supply voltage) and then VLOGIC (logic voltage). This ensures that the internal voltage regulator is properly enabled before the logic circuits are powered up.
• How do I configure the LIS3L02AQ3TR for low-power mode?
  To configure the LIS3L02AQ3TR for low-power mode, set the LPEN (Low Power Enable) bit in the CTRL_REG1 register to 1. This reduces the current consumption of the device, but may also affect its performance and accuracy.
• What is the maximum acceleration range that the LIS3L02AQ3TR can measure?
  The LIS3L02AQ3TR can measure accelerations up to ±2g, ±4g, or ±8g, depending on the range selected by the FS (Full Scale) bits in the CTRL_REG4 register.
• How do I interpret the output data from the LIS3L02AQ3TR?
  The LIS3L02AQ3TR outputs 16-bit, two's complement data for each axis (x, y, z). The data is represented in units of mg (milli-g), with a sensitivity of 1 mg/LSB (least significant bit) for the ±2g range, 2 mg/LSB for the ±4g range, and 4 mg/LSB for the ±8g range.
• What is the purpose of the SELF (Self-Test) bit in the CTRL_REG1 register?
  The SELF bit enables a self-test mode that applies a known acceleration stimulus to the sensor, allowing the user to verify the device's functionality and performance.
