Motion-enabled metering devices
The ADXL362 is an ultra-low power 3-axis MEMS
accelerometer that consumes less than 2 µA at a 100 Hz output
data rate, and 300 nA 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 sensor’s full bandwidth
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 ±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 ADXL362’s normal 550 µg/√Hz is desired, either
of two lower noise modes (down to 175 µg/√Hz typ) may be
selected at minimal increase in supply current.
In addition to its ultra-low power consumption, the ADXL362
has many features to enable true system-level power reduction.
It includes a deep multimode output FIFO, a built-in micropower
temperature sensor, and several activity detection modes including
adjustable-threshold sleep and wakeup operation that can run
as low as 300 nA at a 6 Hz (approximate) measurement rate. A
pin output is provided to directly control an external switch
when activity is detected if desired. In addition, the ADXL362
has provisions for external control of sampling time and/or an
external clock.
The ADXL362 operates on a wide 1.6 V to 3.6 V supply range,
and can interface, if necessary, to a host operating on a separate,
lower supply voltage. The ADXL362 is available in a 3 mm ×
3.25 mm × 1.06 mm package.
