Analog Devices New Smallest Footprint Precision Tactical Grade MEMS IMU Makes Breakthrough in Positioning and Navigation Applications

ADIS16490 IMU

Analog Devices’ new smallest, lightest and lowest power tactical grade Inertial Measurement Unit (IMU) features industry leading precision and stability. The new solutions are touted to deliver the equivalent performance which significantly obsoletes legacy solution which is three times larger and heavy. It finally brings tactical grade stability to applications other than those with unlimited budgets.

The high-performance ADIS16490 IMU paves the way for high-accuracy navigation, guidance, and positioning in applications ranging from aviation and unmanned systems to machine control and precision instrumentation to smart munitions, which were previously impossible due to prohibitive size or cost barriers.

The ADIS16490 IMU delivers:

  • Tactical grade in-run bias stability of 1.8 o/hour and 3.6 micro-g (industry best)
  • Lowest angular random walk (0.09 deg/root-hr ) and velocity random walk (0.008 m/sec/root-hr)
  • Factory calibration on every device, across temperature, providing extremely tight tempcos of 24 ppm/oC (gyro) and 16 ppm/oC (accelerometer)
  • High level of immunity to vibration (0.005 o/sec/g) and shock (2000 g) over extended temperature range

The ADIS16490 is sought to represent Analog Devices’ most advanced IMU, leveraging years of system-level experience and ADI’s best performing angular rate and linear acceleration MEMS cores combined with precision calibration, sensor filtering, and fusion. As a result of this advanced level of integration, engineers now have a product that offers the lowest Gyro Angular Random Walk and Accelerometer Velocity Random Walk to help eliminate jitter in stabilization feedback loops, as well as maintain low positional drift in navigation applications where a carefully balanced combination of low noise, tight alignment, vibration immunity, and wide bandwidth (480 Hz Gyro, 750 Hz Accel) provide the lowest total error for the most challenging system implementations.

ADI will be sampling two new variants of the ADIS16490 IMU by the end of 2016. The ADIS16495 and ADIS16497 IMUs will offer greater dynamic range options, which translate into improved design flexibility and broader application reach for system developers.
