Description

The ADXL345BCCZ is a MEMS-based, 3-axis digital accelerometer from Analog Devices, engineered for precise motion detection and tilt sensing. It utilizes a polysilicon surface-micromachined sensor and signal conditioning circuitry to provide a digital output proportional to acceleration. The device features a built-in 32-level FIFO buffer to minimize host processor intervention and supports activity/inactivity detection, tap sensing, and free-fall detection with programmable thresholds.

Operating from a 2.0V to 3.6V supply, it consumes as low as 23 µA in measurement mode at a 100 Hz output data rate, making it suitable for power-sensitive applications. The robust design ensures reliable performance across an extended industrial temperature range from -40°C to +85°C, with full RoHS compliance for environmental safety.

Frequently Asked Questions

What is the operating voltage range for the ADXL345BCCZ?

The ADXL345BCCZ operates from a single supply voltage between 2.0V and 3.6V. It is directly compatible with standard 3.3V logic levels, making it suitable for integration with microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32 without requiring level shifters.

How do I communicate with this accelerometer? What interfaces are supported?

The device supports both I2C (up to 400 kHz) and SPI (3-wire or 4-wire, up to 5 MHz) digital communication protocols. The interface is selected by controlling the state of the CS (Chip Select) pin. The I2C address is configurable, providing flexibility in multi-sensor setups.

What is the significance of the selectable measurement ranges (±2g, ±4g, ±8g, ±16g)?

The selectable full-scale range allows you to trade off between measurement resolution and maximum detectable acceleration. For high-precision, low-motion applications (like tilt sensing), use ±2g. For high-shock or high-vibration environments, select ±16g to prevent sensor saturation and data clipping.

Does the ADXL345BCCZ require external calibration?

No, the ADXL345BCCZ is factory-calibrated for sensitivity and zero-g offset. The calibration parameters are stored in the device, ensuring accurate measurements out of the package. However, for ultra-high precision applications, user-level system calibration may be performed to account for board mounting alignment.

What are the key power-saving features of this accelerometer?

It features multiple power modes, including a low-power measurement mode (~23 µA at 100 Hz) and a standby mode (< 1 µA). The output data rate (ODR) is programmable from 0.1 Hz to 3200 Hz, allowing you to optimize power consumption based on your application's required sampling frequency.
