October 2006 Rev 1 1/17 17 LIS302ALB MEMS motion sensor 3-axis - ±2g analog output "piccolo" accelerometer Features ■ 3.0V to 3.6V supply voltage ■ ~2mW power consumption ■ ±2g full-scale ■ 3 acceleration channels plus multiplexed analog output ■ Ratiometric output voltage ■ Power down mode ■ Embedded self test ■ 10000g high shock survivability ■ ECOPACK® RoHS and “Green” compliant (see Section 6) Description The LIS302ALB 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. The LIS302ALB 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. The device has three analog acceleration output plus an embedded multiplexer that allows to redirect the analog outputs onto a single pin for operation with a single channel A/D converter. The LIS302ALB 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 LIS302ALB 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.
