LIS332AX STMicroelectronics

LIS332AX MEMS inertial sensor: 3-axis 2 g absolute analog-output ultracompact accelerometer Features Single voltage supply operation 2 g full-scale Excellent stability over temperature Absolute 0-g level and sensitivity LGA-16 (3x3x1.0mm) Factory-trimmed device sensitivity and 0-g level Power-down mode The IC interface is manufactured using a CMOS Embedded self-test process that allows a high level of integration to 10000 g high shock survivability design a dedicated circuit trimmed to better match the sensing element characteristics. ECOPACK RoHS and Green compliant (see Section 7) The LIS332AX has a full-scale of 2 g, and is capable of measuring accelerations over a maximum bandwidth of 2.0 kHz. The device Applications bandwidth may be reduced by using external Tilting applications capacitors. The self-test capability allows the user to check the functioning of the system. Free-fall detection Gaming ST is already in the field with several hundred million sensors which have received excellent Anti-theft systems acceptance from the market in terms of quality, Inertial navigation and motion tracking reliability and performance. The LIS332AX is provided in a plastic land grid Description array (LGA) package. The LIS332AX is an ultracompact low-power 3- Several years ago ST successfully pioneered the axis linear accelerometer that includes a sensing use of this package for accelerometers. Today, ST element and an IC interface to provide an analog has the widest manufacturing capability and signal to the external world. strongest expertise in the world for production of sensors in plastic LGA packages. The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon. Table 1.
