ADI Announces Tactical-Grade Gyroscope

June 10, 2010

The latest iSensor gyro and IMU provide full factory calibration and exceptional stability control in robotics, navigation systems, and other industrial instrumentation applications.

NORWOOD, MA /BUSINESS WIRE/ -- Industrial system designs, involving platform stability, navigation, or precision measurements and diagnostics, rely on multiple sensor inputs. In extreme environments, where shock, vibration, and wide temperature ranges are present, a reliance on multiple sensor types or redundant sensors to compensate for environmental instabilities is common. System design engineers are under growing pressure to reduce this added system complexity and cost within existing and new applications. Analog Devices Inc. (ADI) is helping industrial equipment manufacturers more easily implement stabilization, navigation, and control features by adding two highly integrated and precise MEMS inertial sensors to its product line of iSensor motion sensor products. The new sensors combine tactical grade (<10° per hour) gyroscope performance with ADI's award-winning iSensor integration and factory calibration.

"With tactical-grade gyro performance available in ADI's newest iSensor motion sensor products, complex stabilization and GPS-aided dead-reckoning is more easily enabled."

The ADIS16135 iSensor precision angular rate gyro and the ADIS16385 iSensor six-degrees-of-freedom inertial measurement unit (IMU) are both based on ADI's iMEMS (integrated micro-electromechanical system) inertial sensor technology cores and offer an unmatched 6° per hour bias stability, and angular random walk of 0.75deg;/√hr. Extensive factory calibration results in an unmatched sensitivity of 16 ppm/°C, and bias stability to within 0.003° per second over –40°C to 85°C. The sensors are dynamically compensated and provide a simple user interface and control via a standard SPI and register interface. The ADIS16135 gyro and ADIS16385 IMU are designed for a broad range of industrial and instrumentation applications, including camera stability, antenna alignment, down-hole drilling, and GPS navigation in ships, aircraft, fleet vehicles, agricultural machinery, and factory robotics.

"With tactical-grade gyro performance available in ADI's newest iSensor motion sensor products, complex stabilization and GPS-aided dead-reckoning is more easily enabled," said Bob Scannell, iSensor business development manager, ADI. "For industrial system designers who require the highest levels of gyroscope bias accuracy in extreme environments, the ADIS16135 gyro and ADIS16385 multi-axis IMU achieve the best cost-performance ratio available today."

More About the ADIS16135 iSensor Gyroscope
The ADIS16135 is a high-performance single-axis digital gyroscope with a ± 300° per second measurement range, a low noise level of 0.0122° per second/√hr, and operates over a wide 335 Hz bandwidth using a single 4.85 V to 5.15 V voltage supply. The device is factory calibrated for temperature and voltage drift and provides superior linear acceleration sensitivity of only 0.03° per second/g. It is also interface-compatible with all iSensor products, including the ADIS16385 IMU and others in the ADIS1636X series, further simplifying customer integration and migration plans.

More About the ADIS16385 Six-degrees-of-freedom IMU
The ADIS16385 is a complete inertial measurement unit that includes a ± 300° per second tri-axis gyroscope and a ± 5-g tri-axis accelerometer. Tactical-grade performance of 6° per hour is available on the z axis gyro, with inertial-grade performance provided on the x and y axis, providing a balanced price-performance solution for those applications with a primary axis of concern. The ADIS16385 IMU and the ADIS16135 gyro contain user-configurable internal filtering and multiple condition-monitoring options. To download the data sheet, visit the company's Web site.

Pricing, Availability, and Compatibility
The ADIS16135 gyro and the ADIS16385 IMU are interface-compatible, with current-generation IMUs, such as ADI's ADIS1635x, ADIS1636x, and ADIS1640x. Both devices operate over the temperature range of –40°C to 105°C.
