ADXL366BCCZ-RL7

ADXL366BCCZ-RL7 is an ultra-low power, 3-axis microelectromechanical systems (MEMS) accelerometer that consumes only 0.96µA at a 100Hz output data rate and 191nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL366 does not alias input signals by under sampling but samples the full bandwidth of the sensor at all data rates. The ADXL366 provides 14-bit output resolution. When a lower resolution is sufficient, 8-bit formatted data is also offered for more efficient single-byte transfers. In addition, for ADXL362 design compatibility, 12-bit formatted data is also provided. Measurement ranges of ±2g, ±4g, and ±8g are available, with a resolution of 0.25mg/LSB on ±2g range. In addition to its ultra-low power consumption, the ADXL366 has many features to enable true system-level power reduction. In addition to its ultra-low power consumption, it has many features to enable true system-level power reduction.
