GENERAL DESCRIPTION

The ADXL343 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.

FEATURES

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,
