Analog Devices, Inc. (ADI) today announced a triaxial MEMS accelerometer designed for a wide range of health and industrial applications, including vital signs monitoring, hearing aids and mobility-capable measuring devices. The ADXL367 accelerometer improves power consumption twice as much as the previous generation of the device (ADXL362), while improving noise performance by up to 30 percent. The new accelerometer also provides extended field time, which increases battery life and reduces frequency and maintenance costs.

The ADXL367 consumes only 0.88 µA at an output data rate of 100 Hz and 180 nA when in motion-activated wake mode. Unlike accelerometers, which use cyclic power mode to achieve low power consumption, the ADXL367 does not create an alias for input signals by sampling, but rather takes samples of the sensor’s full bandwidth at all data speeds.

ADXL367 Main features:

  • 200 nW motion detection in wake mode and 970 nW in measurement mode.
  • Deep multimode FIFO output, built-in micro-power temperature sensor, internal ADC for synchronous conversion of additional analog input, single / double touch detection and status machine to prevent false positives.
  • Functions with supply voltages of 1.1 V, which allows operation with a single cell battery without external amplifier converters.
  • Provisions for external control of sampling time and / or external clock.
  • Rich digital features, such as single and double touch, free fall, and activity detection, reduce host microprocessor calculations and further improve system power consumption.
