ADXL362 Lowest Power MEMS Accelerometer
Analog Devices introduces the industry's lowest power MEMS accelerometer, the ADXL362. 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. Examples include hearing aids, home healthcare devices, and motion-enabled metering or power save switches.

The ADXL362 consumes 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates. The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of  plus or minus 2 g,  plus or minus 4 g, and  plus or minus 8 g are available, with a resolution of 1 mg/LSB on the  plus or minus 2 g range. For applications where a noise level lower than the normal 550 μg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 μg/√Hz typical) can be selected at minimal increase in supply current.

Other features enabling true system level power reduction include a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate.

The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ±2 g, ±4 g, and ±8 g are available, with a resolution of 1 mg/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 μg/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 μg/√Hz typical) can be selected at minimal increase in supply current.

Latest Analysis
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
The big picture to this hands-on technology curriculum is to illustrate to students that the future of IoT and IoE (Internet of Everything) development can be created in today’s classroom.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
