FEATURES Ultra low power Power can be derived from coin cell battery 1.8 µA @ 100 Hz ODR, 2.0V supply 3.0 µA @ 400 Hz ODR, 2.0V supply 300 nA motion-activated Wake-up Mode 10nA Standby Current Built-in features for system-level power savings: Adjustable-threshold sleep/wake modes for motion activation Autonomous interrupt processing without need for microcontroller intervention, so the rest of the system can be turned off completely Deep embedded FIFO minimizes host processor load Awake state output enables implementation of standalone motion-activated switch High resolution of 1 mg/LSB Low noise down to 175 µg/√Hz Wide supply and I/O voltage ranges: 1.6 V to 3.6 V Operates off 1.8V to 3.3V rails Acceleration sample synchronization via external trigger On-chip temperature sensor SPI digital interface Measurement ranges selectable via SPI command Small and thin 3 mm × 3.25 mm × 1.06 mm package APPLICATIONS Hearing aids Home healthcare devices Motion-enabled power save switch Wireless sensors Motion-enabled metering devices GENERAL DESCRIPTION The ADXL362 is an ultra-low power 3-axis MEMS accelerometer that consumes less than 2 µA at a 100 Hz output data rate, and 300 nA 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 sensor’s full bandwidth 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 ADXL362’s normal 550 µg/√Hz is desired, either of two lower noise modes (down to 175 µg/√Hz typ) may be selected at minimal increase in supply current. In addition to its ultra-low 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 wakeup operation that can run as low as 300 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 3.6 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. FUNCTIONAL BLOCK DIAGRAM Figure 1. |
