STEVAL-MKI045V1

LPY503AL MEMS motion sensor: dual axis pitch and yaw 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 gyroscope is the combination of one actuator Two separate outputs for each axis and one accelerometer integrated in a single (1x and 4x amplified) micromachined structure. Integrated low-pass filters It includes a sensing element composed by single Low power consumption driving mass, kept in continuos oscillating Embedded power-down movement and able to react when an angular rate is applied based on the Coriolis principle. Embedded self-test A CMOS IC provides the measured angular rate High shock and vibration survivability to the external world through an analog output ECOPACK RoHS and Green compliant voltage, allowing high level of integration and (see Section 5) production trimming to better match sensing element characteristics. Applications STs gyroscope family leverages on robust and Image stabilization for DSC DVC mature manufacturing process already used for the production of micromachined accelerometers. Motion control with user interface ST is already in the field with several hundreds Industrial and robotics million sensors with excellent acceptance from the market in terms of quality, reliability and Description performance. The LPY503AL is a low-power dual-axis LPY503AL is provided in plastic land grid array micromachined gyroscope capable of measuring (LGA) package. Several years ago ST pioneered angular rate along pitch and yaw axes. successfully the usage of this package for accelerometers. Today ST has the widest It provides excellent temperature stability and manufacturing capability and strongest expertise high resolution over an extended operating in the world for production of sensor in plastic temperature range (-40 C to +85 C). LGA package. The LPY503AL has a full scale of 30 /s and is capable of detecting rates with a -3 dB bandwidth up to 140 Hz. Table 1.
