ADXL367BCCZ-RL7

ADXL367BCCZ-RL7 is an ultralow power, 3-axis microelectromechanical systems (MEMS) accelerometer that consumes only 0.89µA at a 100Hz output data rate and 180nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, this device does not alias input signals by under-sampling but samples the full bandwidth of the sensor at all data rates. It always provides 14-bit output resolution. 8-bit formatted data is offered for more efficient single-byte transfers when a lower resolution is sufficient. 12bit formatted data is also provided for device design compatibility. It operates on a wide 1.1V to 3.6V supply range, and can interface, if necessary, to a host operating on a separate supply voltage. It is used in applications such as 24/7 sensing, hearing aids, vital signs monitoring devices, motion-enabled power save switches, motion-enabled metering devices, smart watches with single-cell operation, and smart home.

• Internal power supply regulation for high PSRR, on-chip temperature sensor
• Acceleration sample synchronization via external trigger, internal two-pole antialias filter
• SPI (4-wire) and I²C digital interfaces, cross axis sensitivity is 0.8% typical
• Noise density (normal operation) is 370µg/√Hz typical at (2g range)
• Sensor resonant frequency is 2170Hz typical at (TA = 25°C, VS = 2V, VDDIO = 2V)
• Nonlinearity is 0.5% typical at (TA = 25°C, VS = 2V, VDDIO = 2V)
• Power supply rejection ratio is -59dB typical at (input frequency 100Hz to 1KHz)
• Single-tap and double-tap detection with only 35nA of added current
• Deep 512 sample embedded FIFO minimizes host processor load
• Operating temperature range from -40°C to +85°C, 12-terminal LGA package
