Analog Devices released the ADIS16136 tactical grade iSensor digital MEMS gyroscope, which provides 3.5o/hr typical bias stability in a matchbox-sized module consuming less than 1 watt and weighing 25 grams. The tactical grade (below 10o/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.
The ADIS16136 provides data at rates of up to 2048 SPS (samples per second) and offers an averaging/decimation filter structure for optimizing noise/bandwidth trade-offs. The serial peripheral interface (SPI) 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 mm × 44 mm × 14 mm package.
Four holes are provided for 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.
