Description

The IIS328DQ is an ultra-low-power high-

performance 3-axis linear accelerometer with a

digital serial interface, SPI or I2C compatible.

Recommended for industrial applications

requiring an extended temperature range and

long lifespan, the device features ultra-low-power

operational modes that allow advanced power

saving and smart sleep-to-wakeup functions. The

IIS328DQ has dynamic user-selectable full-scales

of ±2g/±4g/±8g and is capable of measuring

accelerations with output data rates from 0.5 Hz

to 1 kHz. The self-test capability allows the user to

check the functioning of the sensor in the final

application. The device may be configured to

generate an interrupt signal through inertial

wakeup events, or by the position of the device

itself. Interrupt generators are programmable by

the end user on-the-fly. Available in a small, quad,

flat pack no-lead package (QFPN) with a 4x4 mm

footprint, the IIS328DQ corresponds to the trend

towards application miniaturization, and is

guaranteed to operate over a temperature range

from -40 °C to +105 °C.
