3轴陀螺仪测量角速度，通常与加速度计组合在一个通用封装中，以便执行诸如传感器融合（用于3D空间中的方向估计）之类的算法。在这种情况下，我们称其为iNEMO （惯性模块）或更笼统的IMU（惯性测量单元），其中也可包含磁力计。
更高的稳定性、和可靠性
意法半导体的模拟和数字陀螺仪具备了时间和温度稳定性，零速率下的噪声率低于0.01 dps/√Hz。这可以基于运动的应用所需的要求。
3轴陀螺仪采用一种传感架构
这些三轴陀螺仪采用一种独立传感架构来测量3个正交轴上的运动，而市面上的其它解决方案则采用2或3种独立架构。意法半导体的解决方案消除了所有会降低输出信号质量的轴间干扰，从而提高了运动控制度和可靠性。
用于多种应用
意法半导体的陀螺仪能够测量宽量程范围（30 ~ 4000 dps）的角速度，以满足不同应用的要求，从手势识别和图像稳定到轨迹推算以及个人导航。
意法半导体的角速度传感器已被应用到手机、平板电脑、3D指示器、游戏控制台、数码相机和很多其它设备中。
描述
The A3G4250D is a low-power 3-axis angular rate sensor able to provide unprecedented stability at zero rate level and sensitivity over temperature and time. It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a standard SPI digital interface. An I2C-compatible interface is also available.
The sensing element is manufactured using a dedicated micro-machining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers.
The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics.
The A3G4250D has a full scale of ±245 dps and is capable of measuring rates with a user-selectable bandwidth.
The A3G4250D is available in a plastic land grid array (LGA) package and can operate within a temperature range of -40 °C to +85 °C.
