LIS302ALK
MEMS motion sensor 3-axis - 2g analog output "piccolo" accelerometer
Preliminary Data

Features

3.0V to 3.6V supply voltage ~2mW power consumption 2g full-scale 3 axes acceleration channels Ratiometric output voltage Embedded self test Power down mode 10000g high shock survivability ECOPACK RoHS and "Green" compliant (see Section 5) The LIS302ALK has a full scale of 2g and it is capable of measuring accelerations over a maximum bandwidth of 2.0kHz. The device bandwidth may be reduced by using external capacitances. A self-test capability allows the user to check the functioning of the sensor in the final application without thew need to move or tilt the sensor. The LIS302ALK is available in plastic Thin Land Grid Array package (TLGA) and it is guaranteed to operate over an extended temperature range from -40 C to +85 C. The LIS302ALK belongs to a family of products suitable for a variety of applications: Mobile terminals Gaming and Virtual Reality input devices Free-fall detection for data protection Antitheft systems and Inertial Navigation Appliance and Robotics.
LGA-14 (3x5x0.9mm)

Description
The LIS302ALK is a miniaturized low-power three-axis linear accelerometer. It includes a sensing element and an IC interface to provide an analog signal to the external world. The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce motion sensors and actuators in silicon. The IC interface is manufactured using a CMOS process that allows to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The device can be operated from 2.16V to 3.6V.
