ADI Releases Tactical-Grade MEMS Gyroscope

November 10, 2011

The unit rivals fiber-optic gyroscope performance and offers significantly smaller size, lighter weight, and less power consumption.

NORWOOD, MA /BUSINESS WIRE/ -- Analog Devices Inc. (ADI) released for general availability the ADIS16136 tactical-grade iSensor digital MEMS gyroscope, which provides 3.5°/hr. typical bias stability in a matchbox-sized module consuming <1 W and weighing only 25 grams. The new tactical-grade (below 10°/hr. bias stability) iSensor MEMS gyroscope operates autonomously and requires no user configuration before producing precise and accurate rate sensing data, quickly enabling precision-dependent applications, such as platform stabilization and control, navigation, robotics, and medical instrumentation.

"Even more significant is the ADIS16136 gyro's small size (approximately1 cubic in.) and low weight (25 grams). This is minute in comparison with fiber-optic gyros, which can be 10 cubic in. or larger and will enable many new applications for precision angular rate sensing."

More About the ADIS16136
This ADIS16136 is optimized for dynamic performance by combining industry-leading iMEMS technology with ADI's proven signal conditioning expertise. The ADIS16136 provides data at rates of up to 2048 samples per second and offers an averaging/decimation filter structure for optimizing noise/bandwidth tradeoffs. The serial peripheral interface and user register structure provide easy access to configuration controls and calibrated sensor data for embedded processor platforms. Full device-specific calibration over temperature drives the internal compensation, resulting in highly stable sensor output, with no additional test or characterization required. The available wide bandwidth of 380 Hz provides significant advantage to complex stabilization applications. The new gyro ships in a 36 by 44 by 14 mm package. Four holes are provided for simple mechanical attachment, with a standard 24-pin, dual row, 1-mm-pitch connector that supports electrical attachment to a printed circuit board or cable system. Operating temperature range is –40°C to 85°C.
