The ADXL345BBCZ is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface.

Applications:

• Mobile devices: Motion sensing, gesture recognition, and tilt compensation.
• Gaming systems: Motion-based gaming and input.
• Industrial applications: Machine health monitoring and vibration analysis.
• Healthcare: Patient monitoring and activity tracking.
• Consumer electronics: Appliance control, user interface and portable device orientation.
• Disk drive protection: Detects sudden movement or impact to protect data.

Features:

• Small size: Allows for integration into space-constrained applications.
• Low power: Suitable for battery-powered devices.
• 3-axis sensing: Provides acceleration data in three dimensions (X, Y, and Z).
• High resolution: 13-bit resolution provides accurate measurements.
• Tap/double tap detection: Simplifies implementation of user interface functions.
• Activity/inactivity monitoring: Allows for power saving by enabling the device only when motion is detected.
• Adjustable bandwidth: User-selectable bandwidth allows for optimization of noise and power consumption.
• Digital interfaces (SPI/I2C): Easy to interface with microcontrollers and processors.

Benefits:

• Improved system performance: Accurate acceleration data enables more precise control and monitoring.
• Reduced power consumption: Low power operation extends battery life in portable devices.
• Simplified design: Small size and easy interface simplify system integration.
• Enhanced user experience: Motion sensing capabilities enable intuitive user interfaces and gaming experiences.
• Cost-effective solution: Provides high performance at a competitive price.

Additional Details:

The ADXL345BBCZ operates from a supply voltage of 2.0 V to 3.6 V. It has an operating temperature range of -40°C to +85°C. It includes a built-in FIFO memory, which allows for the storage of acceleration data, reducing the need for frequent data reads from the microcontroller. The device is available in a small LGA package.
