LIS352ARTR STMicroelectronics

LIS352AR MEMS motion sensor: 3-axis 2 g analog-outputpiccol accelerometer Features Single voltage supply operation 2 g full-scale 3 acceleration channels plus multiplexed analog output Ratiometric output voltage LGA-14 (3x5x0.9mm) Power-down mode Embedded self-test capacitors. The self-test capability allows the user 10000 g high shock survivability to check the functioning of the sensor in the final ECOPACK RoHS and Green compliant application. (see Section 7) The device has three analog acceleration outputs, plus an embedded multiplexer that allows for Applications redirection of the analog outputs onto a single pin for operation with a single-channel A/D converter. Free-fall detection for data protection ST is already in the field with several hundred Tilting applications million sensors which have received excellent Gaming and virtual reality input devices acceptance from the market in terms of quality, Antitheft systems and inertial navigation reliability and performance The LIS352AR is provided in a plastic land grid Description array (LGA) package. The LIS352AR is a miniaturized low-power 3-axis Several years ago ST successfully pioneered the linear accelerometer belonging to the piccolo usage of this package for accelerometers. Today, family of ST motion sensors. It includes a sensing ST has the widest manufacturing capability and element and an IC interface to provide an analog strongest expertise in the world for production of signal to the external world. sensors in plastic LGA packages. The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce motion Table 1. Device summary sensors and actuators in silicon. Temp. Order code Package Packing The IC interface is manufactured using a CMOS range C process that allows the design of a dedicated circuit which is trimmed to better match the LIS352AR -40 to +85 LGA-14 Tray sensing element characteristics. LIS352ARTR -40 to +85 LGA-14 Tape and reel The LIS352AR has a full-scale of 2 g and is capable of measuring accelerations over a maximum bandwidth of 2.0 kHz. The device bandwidth may be reduced by using external February 2010 Doc ID 16933 Rev 1 1/15 www.st.com 15 Contents LIS352AR Contents 1 Block diagram and pin description . 3 1.1 Pin connections and description 3 2 Mechanical and electrical specifications 5 2.1 Mechanical characteristics . 5 2.2 Electrical characteristics . 6 3 Absolute maximum ratings . 7 4 Terminology 8 4.1 Sensitivity 8 4.2 Zero-g level . 8 4.3 Self-test . 8 4.4 Output impedance . 8 5 Functionality . 9 5.1 Sensing element . 9 5.2 IC interface . 9 5.3 Factory calibration . 9 6 Application hints . 10 6.1 Soldering information 11 6.2 Output response vs. orientation 12 7 Package information 13 8 Revision history . 14 2/15 Doc ID 16933 Rev 1
