Data Sheet

FEATURES

GENERAL DESCRIPTION

Low power: as low as 35 µA in measurement mode and

0.1 µA in standby mode at V_S= 2.5 V

Power consumption scales automatically with bandwidth

Embedded, 32-level FIFO buffer minimizes processor load

Bandwidth of up to 1 kHz

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.

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 V_S

SPI (3- or 4-wire) and I²C digital interfaces

Wide temperature range: −40°C to +85°C

10,000 g shock survival

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.

The ADXL375 is supplied in a small, thin, 3 mm × 5 mm ×

1 mm, 14-lead LGA.

Pb free/RoHS compliant

Small and thin: 3 mm × 5 mm × 1 mm LGA package

APPLICATIONS

Concussion and head trauma detection

High force event detection
