The ADXL362BCCZ-RL7 is a 3-axis Digital Output MEMS Accelerometer that consumes less than 2µA at a 100Hz output data rate and 270nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362BCCZ-RL7 does not alias input signals by under sampling, it samples the full bandwidth of the sensor at all data rates. It 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, ±4 and ±8g are available, with a resolution of 1mg/LSB on the ±2g range. For applications where a noise level lower than the normal 550µg/√Hz of the ADXL362BCCZ-RL7 is desired, either of two lower noise modes (down to 175µg/√Hz typical) can be selected at minimal increase in supply current. In addition to its ultralow power consumption, the ADXL362BCCZ-RL7 has many features to enable true system level power reduction.
