It includes a sensing element composed by single driving mass, kept in continuos oscillating movement and able to react when an angular rate is applied based on the Coriolis principle. A CMOS IC provides the measured angular rate to the external world through an analog output voltage, allowing high level of integration and production trimming to better match sensing element characteristics. ST’s gyroscope family leverages on robust and mature manufacturing process already used for the production of micromachined accelerometers. ST is already in the field with several hundreds million sensors with excellent acceptance from the market in terms of quality, reliability and performance. LPY503AL is provided in plastic land grid array (LGA) package. Several years ago ST pioneered successfully the usage of this package for accelerometers. Today ST has the widest manufacturing capability and strongest expertise in the world for production of sensor in plastic LGA package. Applications ■ ■ ■ Image stabilization for DSC DVC Motion control with user interface Industrial and robotics Description The LPY503AL is a low-power dual-axis micromachined gyroscope capable of measuring angular rate along pitch and yaw axes. It provides excellent temperature stability and high resolution over an extended operating temperature range (-40 °C to +85 °C). 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.
