MEMS motion sensor: dual-axis pitch and yaw ± 30 dps analog gyroscope

The LPY403AL 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 LPY403AL has a full scale of ±30 dps and is capable of detecting rates with a -3 dB bandwidth up to 140 Hz.

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.

ST's family of gyroscopes leverages on the mature and robust manufacturing process already used for the production of micro-machined accelerometers.

ST is already in the field with several hundred million sensors which have received excellent acceptance from the market in terms of quality, reliability and performance.

The LPY403AL is available in a plastic land grid array (LGA) package, which ST successfully pioneered for accelerometers.Today ST has the widest manufacturing capability and strongest expertise in the world for production of sensors in plastic LGA packages.
