Norwood, MA - Analog Devices Inc. announced the launch of its new
iSensor™ family of highly integrated intelligent sensors designed for application-specific sensor processing.
Leveraging a patent-pending advanced integration process, the flagship ADIS16201 iSensor intelligent motion sensor
integrates a dual-axis MEMS accelerometer, a digital temperature sensor, power management circuitry and embedded
firmware. This system-in-a-package approach results in a small, cost-effective, easy-to-use sensor solution that
provides fully calibrated digital outputs for motion and inclination measurements. This combination of functionality
is ideal for industrial applications, such as platform stabilization, machine vibration detection, and motion and
positioning measurement.
“Breakthrough packaging allowed us to add significant signal conditioning and
processing intelligence around the sensor in roughly the same footprint as the sensor-core,” said John Hussey,
vice president, High Speed Signal Processing group, Analog Devices. “This combination of advanced
architectures and embedded intelligence through on-chip firmware dramatically improves sensor performance and
enables a new level of integration for industrial systems customers. The ADIS16201 embeds detection, calibration,
compensation and filtering functions in significantly less space than solutions consisting of discrete
accelerometers and microcontrollers.” Industrial heavy-machine manufacturers have relied on less
accurate, more costly handheld devices containing multiple ICs to measure vibration in applications where the
slightest motion could cause manufacturing defects. With Analog Devices’ ADIS16201 iSensor intelligent motion
sensors, industrial design engineers can now embed sensor technology directly into their systems. This enables a
more cost-effective, more accurate solution for real-time motion measurement, and allows a series of alerts to be
programmed at pre-defined thresholds for acceptable movement and adjustment.
The ADIS16201 combines ADI’s high precision
±1.7 g ADXL203 accelerometer with all required signal conditioning, processing, power management, firmware,
and interfaces to enable a self-contained, programmable sensing solution in a small 9 mm × 9 mm package. The
ADIS16201 offers several features that enhance ease-of-use, while reducing the cost and time associated with
system-level sensor integration. Sensitivity and bias levels are factory calibrated, and can be updated through
field calibration. In addition, frequency response can be modified through digital filtering, and dual alarm
settings are available with user-defined rate/threshold limits and interrupt control. The device also features
application-specific programmable power management options. The digital output data from the sensor is provided via
an industry-standard SPI (serial port interface).
About the iSensor Intelligent Motion
Sensor Family of Products In addition to the ADIS16201 intelligent motion sensor, ADI’s family of
iSensor products includes the ADIS16003 and ADIS16100 devices. The ADIS16003 is a low-cost, low-power
dual-axis accelerometer with an integrated SPI and embedded analog signal conditioning and temperature sensor. The
ADIS16003 measures acceleration with a full-scale range of ±1.7 g and can measure both dynamic acceleration
(e.g., vibration) and static acceleration (e.g., gravity). The ADIS16100 is a functionally complete, low-cost
angular rate sensor (gyroscope) based on ADI’s surface-mircomachining process with an integrated SPI. The
iSensor portfolio of products will continue to grow to include further advancements in embedded intelligence,
performance improvements and ease-of-use features for the important industrial sensor processing
market.
Availability and Pricing The ADIS16201 iSensor intelligent sensor is
available at $28 per unit in 1,000-piece quantities in a laminate-based LGA (land grid array) package and is
sampling now, with full production volume slated for March 2006. The ADIS16003 is in full production now and is
available at $17.75 per unit in 1,000-piece quantities in a laminate-based LGA package. The ADIS16100 is available
at $36.50 per unit in 1,000-piece quantities in a laminate-based LGA package and is sampling now.
