Analog Devices Inc. ADXL362BCCZ-RL7

ADXL362BCCZ-RL7 Description
An ultralow power, 3-axis MEMS accelerometer, the ADXL362 uses less than 2 nA in output data rate mode at 100 Hz and 270 nA in wake-up mode in response to motion. The ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates, in contrast to accelerometers that use power duty cycling to achieve low power usage. The ADXL362 offers 8-bit prepared data for more effective single-byte transfers when a lower output resolution is sufficient. The ADXL362 always offers 12-bit output resolution.

ADXL362BCCZ-RL7 Features
