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.

iis328dq是一个超低功耗高性能的三轴线性加速度计的数字串行接口、SPI或I2C兼容。建议需要一个扩展的温度范围和使用寿命长的工业应用，该设备的功能超低功率操作模式，让先进的节能和智能休眠唤醒功能。iis328dq动态用户可选的全尺度的±2g／±4G /±8G可测量加速度的输出数据率从0.5赫兹到1千赫。自检功能允许用户检查传感器在最终应用程序的功能。该装置可用于产生惯性唤醒事件信号中断，或设备本身的位置。中断发生器是可编程的终端用户的飞行。在一个小的，方形，扁平无引线封装（qfpn）用4x4毫米的足迹，iis328dq对应对应用小型化的趋势，并保证工作在温度范围从- 40°C + 105°C.
