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.
The STMicroelectronics LPY4150AL is a low-power dual-axis micromachined gyroscope designed to measure angular rate along pitch and yaw axes. It operates on a single supply voltage ranging from 2.7V to 3.6V and features a full scale of ±1500 dps with a -3 dB bandwidth up to 140 Hz.
The device provides two separate analog outputs for each axis: one unamplified and one amplified by a factor of 4. It includes integrated low-pass filters, an embedded self-test function, and sleep mode for power saving. The LPY4150AL is available in a plastic land grid array (LGA) package and is suitable for applications such as gaming, pointing devices, remote controls, and industrial robotics.
