ST LPY4150AL MEMS motion sensor: dual-axis pitch yaw ±1500 dps analog gyroscope handbook

The LPY4150AL 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 LPY4150AL has a full scale of ±1500 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.
