The STMicroelectronics I3G4250D three-axis digital output gyroscope is a low-power angular rate sensor that offers unprecedented stability at zero-rate levels and sensitivity over temperature and time.
The I3G4250D includes a sensing element and an IC interface that provides the measured angular rate to the application through a standard SPI digital interface. I2C compatible interface is also provided.
The sensing element is manufactured using a dedicated micromachining process developed by STMicroelectronics, which produces inertial sensors and actuators on silicon wafers. The IC interface is manufactured using a CMOS process that allows a high degree of integration to design specialized circuits and fine-tune them to better match the characteristics of the sensing element.
The I3G4250D has selectable full scale (± 245 / ± 500 / ± 2000dps) and can measure rates at user-selectable bandwidth. The I3G4250D is available in a plastic land grid array (LGA) package and operates over a temperature range of -40C to + 85C.
Applications include industrial, navigation, telematics, motion control with MMI (Human Machine Interface), equipment and robotics.
