Analog Devices Introduces Industry’s Lowest Power MEMS Accelerometer

Business Wire
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance semiconductors for signal processing applications,
introduced today the industry’s lowest power MEMS accelerometer.
The ADXL362, 3-axis, digital MEMS accelerometer operates at 300 nA
in motion sensing wake-up mode, consuming 60 percent less current
than the closest competing sensor in the same mode. In full
measurement mode, the ADXL362 uses 2 μA at a 100 Hz data rate,
using 80 percent less power than competing MEMS accelerometers
operating at the same frequency. This extremely low power
consumption allows the ADXL362 to be used in applications that
require battery life expectancy of months or years, and where
battery replacement can be impractical or dangerous to the
equipment or operator.
ADXL362 MEMS Accelerometer Enables System-Level Power
Savings
In addition to its native low-power operation, the ADXL362 MEMS
accelerometer has additional key features that enable system-level
power efficiency. The ADXL362 can be used as part of an
intelligent, continuously operational, motion-activated switch.
Equipped with an Awake Status output pin, the motion sensor can
instantly trigger a switch that turns on system functions,
bypassing the processor, to further reduce system power.
“Designing for low power requires more than low current draw at
the component level, it also means intelligently managing total
system power by turning system functions on and off at precisely
the correct time,” said Bill Murphy, product line director,
MEMS/Sensors group, Analog Devices. “The ADXL362 leads the industry
in this respect, enabling applications ranging from healthcare to
infrastructure monitoring, where battery life is absolutely
critical.”
The ADXL362 also integrates an enhanced, sample activity
detection function that accurately distinguishes between different
kinds of motion. This eliminates false positives and prevents the
sensor from turning the system on unnecessarily and costing
additional battery life. The ADXL362 MEMS accelerometer embeds a
deep internal FIFO memory block that allows system designers to
record data and stream long data sets, reducing processor load and
saving additional system power.

DARPA Blast Gauge™ Impact Detection System Incorporates ADI
MEMS Technology
The ADXL362 is planned for implementation into the second
generation of DARPA's Blast Gauge™, which was developed at
Rochester Institute of Technology and commercialized by BlackBox
Biometrics to protect U.S. Armed Forces personnel. The Blast Gauge
serves as both a screening tool for medical personnel performing
triage on individuals exposed to a blast and provides detailed data
for the research community unlocking the causes of Traumatic Brain
Injury (TBI.) The initial generation of the blast gauge used ADI's
ADXL345 sensor and has been deployed for a year on thousands of
U.S. soldiers in Afghanistan.
“Using ADI's high-performance MEMS sensors, the Blast Gauge
has proven to reliably detect concussive forces experienced by
the men and women of our Armed Forces. The ADXL362 will
significantly extend battery life in these sealed devices which
utilize a non-rechargeable battery,” said David Borkholder,
chief technology officer of BlackBox Biometrics.
More About the ADXL362 Digital MEMS Accelerometer
Additional features of the ADXL362 digital MEMS accelerometer
include two lower-noise modes that allow the user to roughly halve
the noise at the expense of a few microamps (μA); a built-in
micro-power temperature sensor; and the ability to synchronize the
sampling time to an external trigger. The ADXL362 natively provides
acceleration data with 12-bit resolution, as well as 8-bit
formatted data for more efficient single-byte transfers when a
lower resolution is sufficient. The accelerometer has measurement
ranges of ±2 g, ±4 g, and ±8 g, with a resolution of 1 mg/LSB on
the ±2 g range.
