LY330ALH

LY330ALH MEMS motion sensor: high performance 300 dps analog yaw-rate gyroscope The device includes a sensing element composed of a single driving mass, kept in continuous oscillation and capable of reacting, based on the Coriolis principle, when an angular rate is applied. A CMOS IC provides the measured angular rate to the external world through an analog output voltage, allowing high levels of integration and production trimming to better match sensing element characteristics. LGA-10 (3x5x1 mm) ST s family of gyroscopes leverages on the mature and robust manufacturing process already used for the production of micro-machined accelerometers. Features ST is already in the field with several hundred million sensors which have received excellent 2.7 V to 3.6 V single-supply operation acceptance from the market in terms of quality, Wide operating temperature range (-40 C to reliability and performance. +85 C) High stability over temperature The LY330ALH is available in a plastic land grid Analog absolute angular-rate outputs array (LGA) package, which ST successfully pioneered for accelerometers. Today ST has the Integrated low-pass filters widest manufacturing capability and strongest Low power consumption expertise in the world for production of sensors in Sleep mode plastic LGA packages.
