Messbereich ± 2g / ± 4g / ± 8g / ± 16g

Datenblatt ADXL345

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 accessi-
ble through either a SPI (3- or 4-wire) or I 2 C digital interface.

Features

Ultralow power: as low as 23 μA in measurement mode and
0.1 μA in standby mode at V S = 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 detection
Activity/inactivity monitoring
Free-fall detection
Supply voltage range: 2.0 V to 3.6 V
I/O voltage range: 1.7 V to V S
SPI (3- and 4-wire) and I 2 C digital interfaces
Flexible interrupt modes mappable to either interrupt pin
Measurement ranges selectable via serial command
Bandwidth selectable via serial command
