ADXL345 Datasheet – Digital Accelerometer – Analog Devices

Part Number: ADXL345

Function: Digital Accelerometer

Package: 14-Terminal Land Grid Array [LGA]

Manufacturer: Analog Devices





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. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°.



ADXL345 datasheet



1. Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical)

2. Power consumption scales automatically with bandwidth

3. User-selectable resolution

(1) Fixed 10-bit resolution

(2) 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)

4. Patent pending, embedded memory management system with FIFO technology minimizes host processor load
