Product Details","There is an ADXL362 variant called ADXL362-MI which is applicable to medical implantable and other Class III devices. The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 µA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.","The ADXL362 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 g, ±4 g, and ±8 g are available, with a resolution of 1 mg\/LSB on the ±2 g range. For applications where a noise level lower than the normal 550 µg\/√Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 µg\/√Hz typical) can be selected at minimal increase in supply current.","In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and\/or an external clock.","The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm × 3.25 mm × 1.06 mm package.","Refer to the ADXL362-MI data sheet for information on ADXL362-MI. The ADXL362-MI is processed through a special, high reliability manufacturing flow involving additional process, test, and quality controls to meet the quality and reliability requirements of implantable and other Class III medical devices.
