Description
The AIS326DQ is a three axes digital output
accelerometer that includes a sensing element
and an IC interface able to take the information
from the sensing element and to provide the
measured acceleration signals to the external
world through an SPI serial interface.
The sensing element, capable of detecting the
acceleration, is manufactured using a dedicated
process developed by ST to produce inertial
sensors and actuators in silicon.
The IC interface instead is manufactured using a
CMOS process that allows high level of
integration to design a dedicated circuit which is
factory trimmed to better match the sensing
element characteristics.
The AIS326DQ has a user selectable full scale of
±2g,±6g and it is capable of measuring
acceleration over a bandwidth of 640 Hz for all
axes. The device bandwidth may be selected
accordingly to the application requirements. The
self-test capability allows the user to check the
functioning of the system.
The device is available in plastic quad flat
package no lead surface mount (QFPN) and it is
specified over a temperature range extending
from -40℃ to +105℃.
The AIS326DQ may be used in non-safety
automotive applications, such as；
Anti-theft systems and inertial navigation
Motion activated functions
Vibration monitoring and compensation
Tilt measurements
Black boxes, event recorders
