June 5, 2012 – Analog Devices ( www.analog.com , NASDAQ: ADI), a leader in the high-performance semiconductor market for signal processing applications, today introduced the industry's lowest-power MEMS accelerometer. ADI's ADXL362, a 3-axis digital MEMS accelerometer, operates at 300nA in motion-sensing wake-up mode, consuming 60% less power than the closest competitor sensor in the same mode. In full measurement mode, the ADXL362 consumes 2μA when transmitting data at 100Hz, which is 80% less power than competitor MEMS accelerometers operating at the same frequency. Due to this extremely low power consumption, the ADXL362 can be used in applications where battery life is expected to be months or years, as well as in applications where battery replacement is virtually impossible or could endanger equipment or operators.

ADXL362 MEMS Accelerometer for System-Level Power Saving
In addition to basic low-power operation, the ADXL362 MEMS accelerometer features additional key specifications that improve system-level power efficiency. The ADXL362 can be used as part of a continuously operating intelligent motion-enabled switch. When equipped with an Awake Status output pin, this motion sensor can further reduce system power by immediately triggering a switch that activates system functions without going through the processor.

“Designing low-power products requires not only reducing current consumption at the component level but also intelligently managing overall system power by ensuring system functions start and stop at precise times,” said Bill Murphy, Product Line Director at Analog Devices’ MEMS/Sensor Group. “The ADXL362 is an industry-leading product in this regard and enables applications where battery life plays a critical role, ranging from medical fields to infrastructure monitoring.”

The ADXL362 incorporates enhanced sample motion detection capabilities that accurately distinguish various types of motion. This ensures that it does not react to inaccurate signals and prevents the sensor from unnecessarily operating the system, thereby wasting battery power. The ADXL362 MEMS accelerometer features an internal FIFO memory block, allowing system designers to record data and stream long data sets, which lowers processor load and further reduces system power consumption.

ADI MEMS Technology Applied to DARPA Blast Gauge™ Shock Detection System
ADXL362 is set to be implemented in DARPA's second-generation Blast Gauge™. This product was developed by the Rochester Institute of Technology and commercialized by BlackBox Biometrics for the purpose of protecting the U.S. military. The blast gauge not only serves as a screening tool that enables medical personnel to identify individuals exposed to explosive environments, but also provides detailed data to research groups investigating the causes of traumatic brain injury (TBI). Early blast gauges used ADI's ADXL345 sensor and were distributed to thousands of U.S. troops deployed in Afghanistan for one year.

David Borkholder, Chief Technology Officer at Black Box Biometrics, stated, “By using ADI’s high-performance MEMS sensors, the blast gauge has been proven to reliably detect the vibrational forces experienced by U.S. military personnel. The ADXL362 will significantly extend battery life in these sealed devices where batteries cannot be replaced.”

Additional information regarding the ADXL362 digital MEMS accelerometer
In addition, the ADXL362 digital MEMS accelerometer includes two low-noise modes that allow users to reduce noise by half at the expense of a few microamperes (μA), a built-in micropower temperature sensor, and the ability to synchronize sampling time with an external trigger. The ADXL362 provides acceleration data with 12-bit resolution by default, as well as 8-bit data for more efficient single-byte transmission when lower resolution is sufficient. The measurement range of this accelerometer is ±2g, ±4g, and ±8g, and it supports a resolution of 1mg/LSB in the ±2g range.
