LIS332AR STMicroelectronics

LIS332AR MEMS motion sensor: 3-axis 2 g analog-output ultracompact accelerometer Features Single voltage supply operation 2 g full-scale High stability over temperature Ratiometric output voltage Power-down mode LGA-16 (3x3x1.0mm) Embedded self-test 10000 g high shock survivability ECOPACK RoHS and Green compliant circuit which is trimmed to better match the (see Section 7) sensing element characteristics. The LIS332AR has a full-scale of 2 g, and is Applications capable of measuring accelerations over a Tilting applications maximum bandwidth of 2.0 kHz. The device bandwidth may be reduced by using external Free-fall detection capacitors. The self-test capability allows the user Gaming to check the functioning of the sensor in the final Anti-theft systems application. Inertial navigation and motion tracking ST is already in the field with several hundred million sensors which have received excellent acceptance from the market in terms of quality, Description reliability and performance. The LIS332AR is a miniaturized low-power 3-axis The LIS332AR is provided in a plastic land grid linear accelerometer belonging to the nano array (LGA) package. family of ST motion sensors. It includes a sensing element and an IC interface to provide an analog Several years ago ST successfully pioneered the signal to the external world. use of this package for accelerometers. Today, ST has the widest manufacturing capability and The sensing element, capable of detecting the strongest expertise in the world for production of acceleration, is manufactured using a dedicated sensors in plastic LGA packages. process developed by ST to produce motion sensors and actuators in silicon. The IC interface is manufactured using a CMOS process that allows the design of a dedicated Table 1.
