LPR430AL STMicroelectronics

LPR430AL MEMS motion sensor: dual-axis pitch and roll 300 dps analog gyroscope Features 2.7 V to 3.6 V single-supply operation Wide operating temperature range (-40 C to +85 C) LGA-28 (4x5x1 mm) High stability over temperature Analog absolute angular-rate outputs The LPR430AL has a full scale of 300 dps and is Two separate outputs for each axis capable of detecting rates with a -3 dB bandwidth (1x and 4x amplified) up to 140 Hz. Integrated low-pass filters The device includes a sensing element composed Low power consumption of a single driving mass, kept in continuous oscillation and capable of reacting, based on the Embedded power-down Coriolis principle, when an angular rate is applied Embedded self-test A CMOS IC provides the measured angular rate Sleep mode to the external world through an analog output High shock and vibration survivability voltage, allowing high levels of integration and production trimming to better match sensing ECOPACK RoHS and Green compliant element characteristics. (see Section 6) ST s family of gyroscopes leverages on the Applications mature and robust manufacturing process already used for the production of micro-machined Pointing devices, remote and game controllers accelerometers. Motion tracking with user interface ST is already in the field with several hundred GPS navigation systems million sensors which have received excellent acceptance from the market in terms of quality, Industrial and robotics reliability and performance. LPR430AL is provided in plastic land grid array Description (LGA) package. Several years ago ST pioneered The LPR430AL is a low-power dual-axis successfully the usage of this package for micromachined gyroscope capable of measuring accelerometers. Today ST has the widest angular rate along pitch and roll axes. manufacturing capability and strongest expertise in the world for production of sensors in plastic It provides excellent temperature stability and LGA packages. high resolution over an extended operating temperature range (-40 C to +85 C).
