From Digi-Key, the LIS35DE (497-8549-ND) is an ultra compact low-power three axis linear accelerometer. It includes a sensing element and an IC interface able to provide the measured acceleration to the external world through I²C/SPI serial interface.

The LIS35DE has dynamically user selectable full scales of ±2g/±8g and it is capable of measuring accelerations with an output data rate of 100 Hz or 400 Hz.

The device may be configured to generate inertial wake-up/free-fall interrupt signals when a programmable acceleration threshold is crossed at least in one of the three axes. Thresholds and timing of interrupt generators are programmable by the end user on the fly.

Features:

• 2.16V to 3.6V single supply operation

• 1.8V compatible IOs

• <1mW power consumption

• ±2/±8 user selectable full-scale

• I²C/SPI digital output interface

• Programmable multiple interrupt generator

• Click and double click recognition

• Embedded high pass filter

• 10,000G high shock survivability

• RoHS Compliant package

Applications:

• Free-fall detection

• Motion activated function

• Gaming and virtual reality input devices

• Vibration monitoring and compensation
