ADXL345 Datasheet Digital Accelerometer

Manufacturer: Analog Devices

Datasheet Details

The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g.

Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

The ADXL345 is well suited for mobile device applications.

Data Sheet ADXL345 3-Axis, ±2 g/±4 g/±8 g/±16 g Digital Accelerometer.

Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical).
Power consumption scales automatically with bandwidth.
User-selectable resolution.
Fixed 10-bit resolution.
Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges).
Embedded memory management system with FIFO technology minimizes host processor load.
Single tap/double tap.
