3-Axis, ±200 g Digital MEMS Accelerometer Enhanced Product ADXL375-EP FEATURES GENERAL DESCRIPTION Low power: as low as 35 µA in measurement mode and
The ADXL375-EP is a small, thin, 3-axis accelerometer that
0.1 µA in standby mode at VS = 2.5 V
provides low power consumption and high resolution
Power consumption scales automatically with bandwidth
measurement up to ±200 g. The digital output data is formatted
Embedded, 32-level FIFO buffer minimizes processor load
as 16-bit, twos complement data and is accessible through a
−3 dB bandwidth of up to 1.6 kHz
serial peripheral interface (SPI) (3- or 4-wire) or I2C digital
Bandwidth selectable via serial command
interface.
Shock event detection
An integrated memory management system with a 32-level first in,
Activity/inactivity monitoring
first out (FIFO) buffer can be used to store data to minimize host
Supply voltage range: 2.0 V to 3.6 V
processor activity and lower overall system power consumption.
I/O voltage range: 1.7 V to VS SPI (3- or 4-wire) and I2C digital interfaces
Low power modes enable intelligent motion-based power
10,000 g shock survival
management with threshold sensing and active acceleration
Pb free/RoHS compliant
measurement at extremely low power dissipation.
Small and thin: 3 mm × 5 mm × 1 mm LGA package
The ADXL375-EP is supplied in a small, thin, 3 mm × 5 mm ×
ENHANCED PRODUCT FEATURES
1 mm, 14-terminal land grid array (LGA).
