LPR403AL STMicroelectronics

LPR403AL MEMS motion sensor: dual-axis pitch and roll 30 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 LPR403AL has a full scale of 30 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 Image stabilization for DVC and DSC accelerometers. Image stabilization for camera phones ST is already in the field with several hundred Motion controlled user interface million sensors which have received excellent acceptance from the market in terms of quality, GPS navigation systems reliability and performance. The LPR403AL is available in a plastic land grid Description array (LGA) package, which ST successfully The LPR403AL is a low-power dual-axis micro- pioneered for accelerometers.Today ST has the machined gyroscope capable of measuring widest manufacturing capability and strongest angular rate along pitch and roll axes. expertise in the world for production of sensors in plastic LGA packages. It provides excellent temperature stability and high resolution over an extended operating temperature range (-40 C to +85 C). Table 1.
