GENERAL DESCRIPTION
The ADXL363 is an ultralow power, three-sensor combination consisting of a 3-axis MEMS accelerometer, a temperature sensor, and an on-board analog-to-digital converter (ADC) input for synchronous conversion of an external signal. The entire system consumes less than 2 µA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode.
The ADXL363 communicates via a serial port interface (SPI) and always provides 12-bit output resolution for all three sensors.
FEATURES
Accelerometer, temperature sensor, and provision for third
analog sensor input
All sensors sampled synchronously
Up to 400 Hz ODR
Samples can be synchronized to external trigger
Ultralow power
1.95 µA at 100 Hz ODR, 2.0 V supply, all sensors on
270 nA at 6 Hz motion activated wake-up mode
10 nA standby current
12-bit resolution for all sensors
Acceleration scale factor down to 1 mg/LSB
Temperature scale factor: 0.065°C/LSB (typical)
Built-in features for motion-based system level power savings
Adjustable threshold sleep/wake modes for motion
activation
Autonomous interrupt processing, without need for
microcontroller intervention, to allow the rest of the
system to be turned off completely
Deep embedded FIFO minimizes host processor load
Awake state output enables implementation of
standalone, motion activated switch
