Analog Devices Inc. iSensor MEMS Inertial Measurement Units

Analog Devices iSensor® MEMS inertial measurement unit (IMU) sensors are designed using multi-axis combinations of precision gyroscopes, accelerometers, magnetometers, and pressure sensors. ADI's technology reliably detects and processes multiple degrees of freedom in highly complex applications under dynamic conditions. Offered as plug-and-play solutions, the iSensor MEMS IMU sensors provide full factory calibration, embedded compensation & sensor processing, and a simple programmable interface.
