    ADXL343BCCZ-RL Typical application Circuitry


    The ADXL343BCCZ-RL is part of the ADXL343 series, a family of high-precision, low-power, 3-axis MEMS accelerometers produced by Analog Devices. This series is distinguished for its robust performance in measuring dynamic acceleration resulting from motion or shock as well as static acceleration such as gravity, making it exceptionally suitable for a broad spectrum of applications from mobile devices to sports and health monitoring. The "-RL" suffix generally indicates that the device is provided in a reel package, ideal for automated manufacturing environments.

    1. Power Supply Inputs (VDD, VDD_IO): The ADXL343BCCZ-RL necessitates two power supply connections: VDD for the main supply to the sensor's analog and digital circuits, typically between 2.0V and 3.6V, and VDD_IO for the digital interface logic, which can range from 1.8V to 3.6V. It is imperative to ensure that these supplies are clean and stable, with decoupling capacitors placed adjacent to these pins to mitigate noise.

    2. Ground Connection (GND): The GND pin must be securely connected to the system's ground, providing a stable reference for the accelerometer's operations. This connection is critical for minimizing noise and ensuring accurate accelerometer readings.

    3. Acceleration Outputs (XOUT, YOUT, ZOUT): The ADXL343BCCZ-RL offers analog outputs for each of the three axes (XOUT, YOUT, ZOUT), which can be interfaced with the ADC of a microcontroller for digitization. Accurate acceleration measurements require appropriate scaling and calibration according to the specified sensitivity and zero-g bias levels.

    4. Digital Interface (CS, SDO/ALT ADDRESS, SDA/SCL, SCLK): This device supports both SPI and I2C communication protocols. In SPI mode, the CS pin acts as the chip select, and SDO serves as the serial data output. For I2C communication, the CS pin tied high selects the I2C mode, and the SDO/ALT ADDRESS pin can set an alternate I2C address. SDA/SCL functions as the data and clock lines for I2C or as the serial data input for SPI, with SCLK providing the serial clock in SPI mode.

    5. Interrupt Pins (INT1, INT2): The ADXL343BCCZ-RL is equipped with two interrupt outputs, INT1 and INT2, configurable to indicate various events like motion detection or free-fall. These pins can be connected to a microcontroller's interrupt inputs to facilitate prompt processing of such events.

    6. Self-Test Function (ST): The self-test pin (ST) is used to engage the device's internal self-test mechanism, verifying the accelerometer's mechanical and electrical integrity. Activating this function produces a known shift in the output, aiding in system diagnostics and sensor validation.

    7. PCB Layout Recommendations: Designing the PCB layout demands careful consideration to minimize interference with the accelerometer's sensitive analog outputs. Short and direct power and ground connections are recommended, and a solid ground plane can help reduce noise. Additionally, separating analog and digital sections of the circuit can further enhance performance.

    8. Mechanical Installation: Proper mechanical installation of the ADXL343BCCZ-RL is essential for accurate motion sensing. The device should be mounted securely to avoid any undue mechanical stress or board flexure that might influence the acceleration readings.

    In summary, integrating the ADXL343BCCZ-RL into a system requires meticulous attention to power supply integrity, accurate connection of the analog outputs for acceleration measurement, careful configuration of the digital interface, and the effective use of interrupt outputs for event detection. Additionally, considerations for PCB layout and mechanical mounting are crucial to fully leverage the capabilities of the ADXL343BCCZ-RL in various application scenarios requiring precise 3-axis acceleration data.
