Analog Devices' Inertial Sensor Reduces Cost and Complexity of
Industrial Motion Control Designs
- ADI’s ADIS16365 sensor offers 50 percent
better bias stability and 20 percent more power efficiency, while
reducing implementation time for high-end navigation systems by up to
one year.
NORWOOD, Mass. (Business Wire EON/PRWEB ) June 9, 2008 --
Analog Devices, Inc. (ADI), a
global leader in high-performance semiconductors for signal processing
applications, is expanding its iSensor™
intelligent sensor product family with a new six-degrees-of-freedom (6
DoF) inertial sensor. The ADIS16365 IMU (inertial measurement unit)
combines high-performance, simplicity, and an improved data interface
that delivers faster response times and lowers power consumption
relative to other IMUs in its class. The ADIS16365 makes complex motion
sensing design significantly easier and more cost-effective for
industrial engineers developing high-performance platform control and
navigation equipment. The new IMU reduces power consumption by at least
20 percent, boasts an approximate 10 times improvement in start-up time
and improves bias stability by up to 50 percent, lowering noise
sensitivities that impede navigation accuracy. In addition to
traditional industrial vehicle navigation systems, the ADIS16365’s
low noise and fast response time also benefit a wide range of platform
stability applications, such as vehicle mounted antennas and cameras.
Improved GPS Navigation
The ADIS16365 can be used anywhere high-performance motion control and
feedback is required. In vehicles that rely on GPS satellite navigation
to maintain accurate position information, such as high-end agricultural
equipment, the IMU enhances their performance by immediately detecting
small shifts in the position of the GPS antenna due to rough terrain.
This allows for real-time signal correction and provides the highest
degree of heading accuracy. Additionally, a vehicle-mounted camera or a
factory automation robotic arm can rely on the ADIS16365’s
fast response time and excellent stability to maintain ultra-fine
resolution even under erratic conditions.
“Most inertial motion sensors available today
offer a low level of integration and require a high degree of factory
calibration,” said Andy Garner, product line
director for iSensor intelligent sensor products, Analog Devices. “The
ADIS16365 comes fully calibrated and compensated for temperature,
voltage and other sensitivities. This means customers receive meaningful
data from the device immediately, without requiring additional motion
testing or system integration. With its improved stability and
feature-rich interface, the ADIS16365 significantly reduces the cost,
time and risk of implementation for our customers. The new IMU fills the
considerable void between large, expensive IMUs and less integrated
sensors that leave much of the design testing and cost burden to the
customer.”
ADIS16365 Provides Superior, Accessible and Affordable Performance
IMU sensor implementation involves complex electro-mechanical design,
including many sensor-to-sensor and environmental interdependencies.
Traditional solutions are more expensive and also highly customized to a
narrow class of applications. The factory calibrated and programmable
ADIS16365 simplifies the process of implementing full IMU sensor
capability, and provides affordable, precision 6 DoF sensing to the
broadest range of customers and applications. The device includes
several unique features that further reduce design time and complexity,
including an automatic sensor point-of-reference realignment, digital
range scaling, dynamic environmental compensation, autonomous self test,
and embedded sensor condition monitoring. The device leverages Analog
Devices’ proprietary motion and calibration
testing processes to capture sensor data and alignment compensations
across all three axes, which are then embedded within the IMU, along
with calibration for voltage variances, temperature variances, and other
influences, all of which are then dynamically compensated in-use and are
transparent to the user.
The ADIS16365 is backwards compatible with other iSensor 6 DoF
sensors and includes a faster data access interface, additional system
I/O, a higher dynamic range accelerometer (17g), and an extended
temperature range of –40 degrees C to +105
degrees C.
Harnessing ADI’s MEMS Expertise for
Six-Degrees-of-Freedom Motion
Designed using Analog Devices’ world-class iMEMS®
Motion Signal Processing Technology™, the
ADIS16365 IMU combines three gyroscopes and three accelerometers to
provide 6 DoF motion sensing. With the aid of embedded features such as
the Precision AutoNull, and an outstanding 0.05o/sec/g
dynamic linear acceleration compensation factor, equipment
designers can achieve in-run bias stability of 0.009o/sec
or better without having to perform further motion testing. For
industrial applications, the ADIS16365 achieves unprecedented
performance levels and significantly reduces post-processing complexity
and implementation cost for the system designer. The new IMU sensor
includes a programmable SPI (serial peripheral interface) port that
provides easy access to device features, such as digital filtering,
sample-rate, power-management, self-test, and sensor condition status
and alarms. The sensor, smaller than a 1-inch cube, is
footprint-compatible with previous generations. With only power supply
and SPI connections, the device is fully in-system tunable, allowing
designers to quickly and easily debug their system and experiment with
different configurations for design optimization.
Pricing and Availability
The ADIS16365 is sampling now and is priced at $375 per unit in
1,000-unit quantities. The device is housed in a compact module
measuring 23 mm × 23 mm ×
23 mm. For more information, visit www.analog.com/pr/ADIS16365.
