  • The AIS328DQ is an ultra low-power high performance 3-axis linear accelerometer with a digital serial interface SPI standard output. An I2C compatible interface is also available. The device features ultra low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions. The AIS328DQ 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. Thresholds and the timing of 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 AIS328DQ is able to respond to the trend towards application miniaturization, and is guaranteed to operate over a temperature range from -40 °C to +105 °C.

    Key Features

    • Wide supply voltage range: 2.4 V to 3.6 V
    • Low voltage compatible IOs: 1.8 V
    • Ultra low-power mode consumption: down to 10 μA
    • ±2g/±4g/±8g dynamically selectable full-scale
    • SPI / I2C digital output interface
    • 16-bit data output
    • 2 independent programmable interrupt generators
    • System sleep/wakeup function
    • Extended temperature range: -40 °C to 105 °C
    • Embedded self-test
    • High shock survivability: up to 10000 g
    • ECOPACK® RoHS and “Green” compliant
    • AEC-Q100 qualification
