LPR510AL MEMS motion sensor: dual axis pitch and roll 100/s analog gyroscope Preliminary data Features 2.7 V to 3.6 V single-supply operation Wide operating temperature range (-40 C to +85 C) LGA-16L (5x5x1.5mm) High stability overtemperature Analog absolute angular-rate output The LPR510AL has a full scale of 100 /s and is capable of detecting rates with a -3 dB bandwidth Two separate outputs for each axis up to 140 Hz. The gyroscope is the combination (1x and 4x amplified) of one actuator and one accelerometer integrated Integrated low-pass filters in a single micromachined structure. Low power consumption It includes a sensing element composed by single Embedded power-down driving mass, kept in continuous oscillating movement and able to react when an angular rate Embedded self-test is applied based on the Coriolis principle. High shock and vibration survivability A CMOS IC provides the measured angular rate ECOPACK RoHS and Green compliant to the external world through an analog output (see Section 5) voltage, allowing high level of integration and production trimming to better match sensing Applications element characteristics. GPS navigation systems STs gyroscope family leverages on robust and mature manufacturing process already used for Motion tracking the production of micromachined accelerometers. Pointing devices, remote and game controllers ST is already in the field with several hundreds Motion control with user interface million sensors with excellent acceptance from Industrial and robotics the market in terms of quality, reliability and performance. Description LPR510AL is provided in plastic land grid array The LPR510AL is a low-power dual-axis (LGA) package. Several years ago ST pioneered micromachined gyroscope capable of measuring successfully the usage of this package for angular rate along pitch and roll axes. accelerometers. Today ST has the widest manufacturing capability and strongest expertise It provides excellent temperature stability and in the world for production of sensor in plastic high resolution over an extended operating LGA package. temperature range (-40 C to +85 C).
