GENERAL DESCRIPTION
The ADXL375 is a small, thin, 3-axis accelerometer that provides low power consumption and high resolution measurement up to ±200 g. The digital output data is formatted as 16-bit, twos complement data and is accessible through a SPI (3- or 4-wire) or I2C digital interface.
An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

FEATURES
Low power: as low as 35 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V
Power consumption scales automatically with bandwidth
Embedded, 32-level FIFO buffer minimizes processor load
Bandwidth of up to 1 kHz Bandwidth selectable via serial command
Shock event detection
Activity/inactivity monitoring
Supply voltage range: 2.0 V to 3.6 V
I/O voltage range: 1.7 V to VS
SPI (3- or 4-wire) and I2C digital interfaces
Wide temperature range: −40°C to +85°C
10,000 g shock survival
Pb free/RoHS compliant
