Product overview
Description
The IIS328DQ is an ultralow-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 ultralow-power operational modes that allow advanced power saving and smart sleep-to-wake-up functions. The IIS328DQ has dynamic user-selectable full scales of ±2g/±4g/±8g and can measure 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 wake-up 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 package, no-lead (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.
