ADXL344 Data Sheet
FEATURES GENERAL DESCRIPTION Multipurpose accelerometer with 10-to 13-bit resolution for
use in a wide variety of applications
Digital output accessible via SPI (3-and 4-wire) and I2C
Built-in motion detection features make tap, double-tap,
activity, inactivity, orientation, and free-fall detection
trivial
User-adjustable thresholds
Interrupts independently mappable to two interrupt pins
Low power operation down to 23 µA and embedded FIFO for
reducing overall system power
Wide supply and I/O voltage range: 1.7 V to 2.75 V
Wide operating temperature range (−40°C to +85°C)
10,000 g shock survival
Small, thin Pb free, RoHS compliant 3 mm × 3 mm × 0.95 mm
LGA package The ADXL344 is a versatile 3-axis, digital-output, low g MEMS
accelerometer. Selectable measurement range and bandwidth and
configurable, built-in motion detection make it suitable for sensing
acceleration in a wide variety of applications. Robustness to
10,000 g of shock and a wide temperature range (−40°C to +85°C)
enable use of the accelerometer even in harsh environments. …
