ADIS16355 High-Precision Tri-Axis Inertial Sensor - Analog Devices

Leveraging its iMEMS Motion Signal Processing Technology, Analog Devices introduced the ADIS16355 High-Precision Tri-Axis Inertial Sensor which allows industrial designers to include sophisticated motion analysis and navigational dead reckoning functions into their systems. By detecting tiny shifts in linear acceleration and angular movement the ADIS16355 allow vehicles to remain on course until a lost GPS signal is restored. The ADIS16355  Inertial Sensor can be used in highly sensitive robotic and other motion control devices, where the Inertial Measurement Unit (IMU) helps make certain that precision movements can be accurately repeated thousands of times.

Easily incorporated into industrial system designs where performance is enhanced by precise motion analysis and control, the ADIS16355 enables designers to realize up to 12 months faster development times. The new Inertial Measurement Unit extends ADI's award-winning iSensor intelligent sensor product family, which was introduced to meet the growing demand for MEMS (Micro Electro Mechanical System) motion sensors in industrial markets. The company has shipped more than 300 million iMEMS motion sensors to date.

Applications of ADIS16355 Tri-Axis Inertial Sensor includes:

• Guidance and control
• Platform control and stabilization
• Motion control and analysis
• Inertial Measurement Units
• General Navigation
• Image stabilization
• Robotics

The ADIS16355 Tri-Axis Inertial Sensor  provides six-degrees-of-freedom motion sensing, embedded calibration and sensor processing, sensor-to-sensor cross compensation, and significantly improved signal stability (in-run bias stability of 0.015 deg/sec) in a form factor smaller than a 1-inch cube. Factory calibration and embedded cross-axial alignment compensation enable designers without sensor expertise to quickly, easily, and cost-effectively integrate motion sensing technology to add an entirely new dimension of performance to their applications. Both the ADIS16355 and ADIS16350 include a programmable SPI (serial peripheral interface) port that provides easy access for programming features such as filtering, sample-rate, power-management, self-test, and sensor condition status and alarms. The devices are fully in-system tunable, allowing designers to quickly and easily debug their systems and experiment with different configurations for design optimization. The ADIS16355 Inertial Sensor  provides precise and stable sensor response, and the ADIS16350 offers a lower cost alternative for less sensitive applications.

The ADIS16355 Inertial Sensor is a multi-axis motion sensor that combines gyroscopes and accelerometers to measure all six possible degrees of mechanical freedom (6DOF); linear motion in the X, Y, and Z axes and rotation around the X, Y, and Z axes. Other less integrated sensors require designers to perform complex, costly, and time-consuming motion testing and calibration across multiple axes before they can be assured the devices will provide accurate and stable feedback. Analog Devices overcomes this barrier by submitting the ADIS16355 Tri-Axis Inertial Sensor to a comprehensive factory calibration process and providing the new sensor with a simple, programmable interface to ensure it is both highly precise and ready for integration right out-of-the-box. The ADIS16355 Inertial Sensor  also includes full-temperature-range calibration, versus the room temperature calibration available in the ADIS16355 Inertial Sensor , and provides a superior bias temperature stability of 0.005 deg/sec/°C.

50 Times More Accurate and Easy to Integrate
With similar devices ranging in price from several hundred to several thousand dollars, many applications have been unable to afford the level of precision enabled by the ADIS16355 and ADIS16350, which also provide a 50-times improvement in sensor accuracy compared to other off-the-shelf inertial sensors. A more significant barrier is that the complexities involved in integrating and testing a complete solution starting from the basic sensors presents an extremely complex design challenge. The outstanding cost-performance ratio of the ADIS16355 and ADIS16350 is complemented by unprecedented ease of use, which ensures industrial designers can quickly integrate motion sensing functions into a range of applications.
