LPR503AL MEMS motion sensor: dual axis pitch and roll 30/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 LPR503AL has a full scale of 30 /s 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. The gyroscope is the combination 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 Embedded self-test movement and able to react when an angular rate High shock and vibration survivability is applied based on the Coriolis principle. ECOPACK RoHS and Green compliant A CMOS IC provides the measured angular rate (see Section 5) to the external world through an analog output voltage, allowing high level of integration and production trimming to better match sensing Applications element characteristics. Image stabilization for DVC and DSC STs gyroscope family leverages on robust and Image stabilization for camera phones mature manufacturing process already used for Motion controlled user interface the production of micromachined accelerometers. GPS navigation systems ST is already in the field with several hundreds million sensors with excellent acceptance from Description the market in terms of quality, reliability and performance. The LPR503AL is a low-power dual-axis micromachined gyroscope capable of measuring LPR503AL is provided in plastic land grid array angular rate along pitch and roll axes. (LGA) package. Several years ago ST pioneered successfully the usage of this package for It provides excellent temperature stability and accelerometers. Today ST has the widest high resolution over an extended operating manufacturing capability and strongest expertise temperature range (-40 C to +85 C). in the world for production of sensor in plastic LGA package.
